Document Summary

Organic chemistry the chemistry of carbon and its compounds. 1-1: the scope of organic chemistry: an overview. Funcional groups determine the reacivity of organic molecules. Alkanes molecules composed of only carbon and hydrogen atoms connected by single bonds. Contain no funcional groups therefore are basic scafold of organic molecules. Reacions are the vocabulary and mechanisms are the grammar of organic chemistry: reacion mechanism the underlying details of the reacion, reacion intermediate a species formed on the pathway between reactants and products. 1-2: coulomb forces: a simpliied view of bonding. Coulomb"s law of electric charge: opposite charges atract each other, like charges repel each other. Atracing force = constant [(+) charge (-) charge]/distance2: bond strength the energy released as neutral atoms are brought together, bond length the point at which no more energy is released. The balance between the atracive forces of electrons and protons and repulsive force of protons. 1-3: ionic and covalent bonds: the octet rule.

Organic chemistry is a branch of chemistry that is based on the chemistry of carbon. Answer the following questions based on the models you built containing carbon as one of the central atoms.

a) What types of hybridization did you find in these molecules (around C)?

b) What was the most common type of hybridization around a central carbon?

c) For the most common hybridization how many total domains were there? How many of these were bonding domains? How many were non-bonding (lone pairs)?

Answer question one for molecules containing oxygen as one of the central atoms.

Answer question one for molecules containing nitrogen as one of the central atoms.

Here are several oxygen containing molecules that include oxygen to oxygen bonds. Draw the Lewis structure for each one based on the suggested framework.

a) Ozone, O3 ( not in a ring) OâOâO

b) hydrogen peroxide, H2O2 HâOâOâH

c) How does the electronic geometry and molecular shape of ozone differ from the other oxy- gen containing compounds that you have considered?

d) Do you think that geometry of ozone affects its reactivity? Look up ozone and its chemistry. Report your source and a few things you discover about the reactivity of ozone. Be sure that you use you own words to summarize. Do not plagiarize!

Hydrocarbons are organic molecules that solely consist of hydrogen and carbon atoms. These compounds are considered saturated if they contain the maximum number of hydrogen atoms. Degrees of unsaturation are structural features that cause a compound to have less than the maximum number of hydrogen atoms possible, and cause the hydrocarbon to be considered unsaturated. In hydrocarbons, degrees of unsaturation consist of ring structures and pi bonds (double and triple bonds). The following formulas can be used to determine whether a molecular formula represents an alkane, alkene, or alkyne (assuming that the hydrocarbons are not ring structures, and that the unsaturated compounds only have one double or triple bond).

Alkanes: CnH2n+2

Alkenes: CnH2n

Alkynes: CnH2nâ2

Part F: some functional groups
