1/9/17 -Chapter I-Organic Chemistry
Organic Chemistry -Structure and function of organic molecules
=focuses mainly on Carbon
Structure and function are strongly correlated .(Structure determines function)
Reactants Products ,C-
IBreak bond)(Form bond)HYN NH2
-produced by an organism (def.1828 )
*But in 1828 , it was shown that the three components Of urea could be cooked
to form urea (i. e.
making an organic molecule who an organism )
So now ...Organic -any compound that contains carbon atom
1.) Organic chemistry is essential for understanding DNA ,RNA ,and protein .
3.) Antibiotic How organic Chem relates to medicine
4.) Taxol (anticancer )
-Has lowest potential energy,
is the most stable
EB• to Making abond →releasing energy
:B 2.Breaking abond →absorbing energy .
loloumbsLaw_ Study !
Bonds have specific lengths . If A and Bare forced too e- e-
,their electrons start repelling each other
'iA←B and potential energy increases .Stability decreases .AB
Types of Bonds -covalent ,ionic ,polar covalent,coordinate
FAIT electrons are equally shared
OB e- no longer belong to either atom
ff~B Adonates its e- ,becomes positively charged.
Bhas gained an e- ,so becomes negative .
Positive and negative are strongly attracted
by electrostatic forces .
one §y A →BAgives e. to B,but *also called
still shares them
,not Dativ bond
quite ionic ,not quite covalent
Example -Follows the Octet Rule Nobeltasest
He Have full octet in
H± -wants another e- to be He New
-wants to give e- away to be He Art 8's
-wants to give e
away to be Ne Kr2 's ''8's
it give or get 4?
-wants another e
-to be Ne
wants another e
-to be Ar
Na +Cl →Nat Ci -ionic bond
HO +FO (each wants le ,what to do ?)
Special Case -Carbon
Energy wise ,it's Very difficult to lose 4e -
or gain e-

67 million organic molecules
have been discovered
Hydrogen 22 7dose enough to be
Carbon 2.6 equal
Fluorine 4.0 ←highest,tries hardest to get e-
H8F is actually like IT8k ←Polar Covalent
