#1. Using curved arrows to symbolize electrons, write a complete reaction mechanism for the bromination of acetanilide to create the product. Include the resonance structures for any charged, delocalized intermediates that are involved.

#2. Why does performing the experiment at 0 degrees Celsius help you identify some of the relative rates of reactivity?

#3. Explain why a methyl group is a mildly activating group while a methoxy group is strong activating.

#4. Explain why-- NH2 act as an activator and-- NO2 act as a deactivator. Include resonance and charges in your explanation.

#5. Draw ALL of the intermediate resonance structures that would occur if bromine were added to anisole. Draw the possibilites for ortho-addition, meta-addition, and para-addition and explain why some addition sites will be preferred using your resonance structures.

Using acetanilide, which is an activating group like aniline, show the mechanism for para addition. Include all resonance structures. Explain why para addition, like ortho addition, is favored when an activating group is on the ring.

I included the lab itself too, since question 3 and 4 can't be answered without the lab

1. Compare the reactivity of PhNH3? and PhNH2 under bromination conditions. Classify each as an activating or deactivating group and explain your reasoning. Hint: draw out the complete structure of each showing all lone pairs.
2. Show all aniline resonance structures involving donation of the –NH2 lone pair into the aromatic ring. Using these resonance structures, explain why –NH2 is an ortho, para directing group.

MINI-PROJECT: DIGITAL MEDIA ASSIGNMENT INSTRUCTIONS

OVERVIEW

The overall idea of social media is to integrate technology and social interactions to create value

for users. In doing so, this often will help solve consumer problems While last week you may

have created a traditional side-by-side television ad that could be used before a YouTube video,

this week you are creating THE video, not the ad.

In this Module: Week video entitled “Content is King,” I gave the example of MakeUp.com,

created by L’Oreal, which gives make-up advice without pushing their brand. That is what I am

looking for in these videos. Ask yourself these questions:

• “How can I create a video that improves the life of my target audience?”

• “Does my video bring value or just noise?”

• “Is my video something my target audience would search for on YouTube?

• “Is it a video my target audience would share on social media?”

INSTRUCTIONS

Design and record a short, 30–to–90 second, video ad for YouTube that follows Andrews and

Shimp’s (2018) definition of content marketing: “producing, curating, and sharing (marketer)

content that is based on customers’ needs and delivers visible value” (p. 479).

1. Start by writing an advertising brief. The brief should contain the following:

• Goal of the video (pick one of your IMC goals from Andrews & Shimp Chapter 8–1a

(p.161).

• Target audience (same as Discussion Board 1).

• Specific topic of the video. The video needs to provide useful information for your target

audience, strike an emotional connection, or incentivize user-generated content. I am not

looking for a commercial that people want to skip, but a video that people search for or

want to share on social media because it adds value.

2. Write your script:

• Time your script and edit to get it short enough.

• Use short sentences.

• Use an engaging, conversational tone.

• Do a table read: gather your friends and family and read your script as if you are

shooting. Replace any words that do not sound conversational.

• Again, the script must add value. Think of the videos that you search for on YouTube

or the videos that you share on social media. That is the goal!

3. Produce the video:

• Record your video production. Light the talent from the side, not overhead. Consider

background. Edit your video. YouTube has many tuturials on editing videos from your

laptop or phone. Check out the many video apps.

• One easy to use video app is the FREE lumen5 APP. Super easy to use. Just cut and

A company manufactures two products (A and B) and the profit per unit sold is £3 and £5 respectively. Each product has to be assembled on a particular machine, each unit of product A taking 12 minutes of assembly time and each unit of product B 25 minutes of assembly time. The company estimates that the machine used for assembly has an effective working week of only 30 hours (due to maintenance/breakdown). Technological constraints mean that for every five units of product A produced at least two units of product B must be produced. Formulate the problem of how much of each product to produce as a linear program. Solve this linear program graphically. The company has been offered the chance to hire an extra machine, thereby doubling the effective assembly time available. What is the maximum amount you would be prepared to pay (per week) for the hire of this machine and why

Draw 3 different reaction pathways for meta, ortho, and parasubstitution of a halogen (e.g. Br2 in FeBr3) onto nitro benzene.Each pathway should have all resonance structures.



After you have the resonance structures for each substitutiondrawn, examine them carefully and decide which set of resonancestructures is more (or less stable), and decide whether anitro-group will direct electrophilic aromatic substitution tooccur at the ortho and/or meta and/or para positions (relative tothe nitro group).

In electrophilic aromatic substitution, a nitro substituent is: ______________. Please explain why you chose your answer.

1.Which of the following would react faster than benzene in an electrophilic aromatic substitution reaction?

2.Which of the following would react slower than benzene in an electrophilic aromatic substitution reaction?

3.If an electrophile was added to acetophenone via an electrophilic aromatic substitution, at what position(s) of the ring would the electrophile add?

4.If an electrophile was added to toluene via an electrophilic aromatic substitution, at what position(s) of the ring would the electrophile add?

5.If an electrophile was added to nitrobenzene via an electrophilic aromatic substitution, at what position(s) of the ring would the electrophile add?

Arrange the following compounds in order of decreasing reactivity toward electrophilic aromatic substitution: (1) toluene; (2) phenol; (3) fluorobenzene; (4) nitrobenzene; (5) acetophenone

Arrange the following groups of compounds in order from most reactive to least reactive toward electrophilic aromatic substitution.

1. Benzene, ethylbenzene, chlorobenzene, nitrobenzene, anisole.

2. Toluene, p-cresol, benzene, p-xylene.

4. p-Methylnitrobenzene, 2-chloro-1-methyl-4-nitrobenzene, 1-methyl-2,4-dinitrobenzene, p-chloromethylbenzene.

1. Indicate how you could distinguish between the following pairs of compounds by using infrared spectroscopy.

. Precisely describe how you would use IR technique to distinguish between the following pairs

of compounds, cite the approximate wavenumbers:

a) Butanal and 2-butanone

Describe how you can distinguish between aromatic and alkenefunctional groups using wavenumbers, peak intensity, and peakshape.

I want to read the functional group using IR wavenumber

Answer the following question

Hi, my question is about Pareto optimal.

There are 2 consumers and 2 commodities. Consumer A's initial endowment is 4 units of good x and 1 unit of y, and the utility function is U=x*y. Consumer B's initial endowment is 0 unit of x and 7 units of B, and the utility function is U=min{x,y}.

Question: 1) show the locus of Pareto optimal allocations.

2) let good x be the numeraire (price=1) and p denote the price of goody. Write the expression for the amount of goody that consumer B will demand at these prices.

Please show all work and thank you in advance for your help!

Consider the following economy with production.  There is a worker endowed with 1 unit of time, which can be allocated either to leisure or labor.  There is a firm with a technology that turns a worker’s labor (the complement of his leisure) into bread.  That technology satisfies: b(l)=l^(1/2)

Where l∈[0,1]  denotes the worker’s labor and b(l) is the amount of bread produced as a function of labor input. The  worker’s  utility  function  from  labor  supplied  and bread consumed is: u(l,b) =αln(b)−l,0< α <2

1. What is the set of Pareto optimal allocations in this economy? 

2. Provide prices and an allocation that, together, constitute a competitive equilibrium in this economy. 

Oxygen tank is necessary for mountain climbing. A person purchased a 5L oxygen tank in a store at the bottom of a mountain (i.e., room temperature is 25⁰C). When he/she climbs to the top of the mountain, 60% of the oxygen in the tank is used. Please determined the pressure decrease (in percentage) if the temperature at the top of the mountain is -10⁰C.
