Organic chemitry chapter 1
intro to o chem
why were Organic compounds often harder to isolate or purify?
Back then people used to think the reason Irganic compounds had curious properties was "vital force"
VItal force was almost knocke dout when a chemist runed ammonium cyanate into rea (comon organic compound in urea)
Organic compounds defined as compounds with carbon. inorganic lack carbon
the reponses of our body to medicine are a result of reactions guided by the guiding principles of organic chemistry (deep undertanding of those principles = new drugs)
structural theory of matter
substtance defined by arragement of atoms rather than chemical formula
constitutional isomers
have different properties physical properties
CARBON typically forms 4 bonds so its tetravalent
NItrogen forms 3 bonds so trivalnet
Oxygen 2 bonds divalent
Electrons, Bonds, and Lewis Structures
what are bonds
glue that holds atoms together
A covalent bond is the result of 2 atoms sharing a pair of electrons
when H forms a bond it dereases in energy which means negative delta H
electrons are capable of oving in such a way that it minimizes repulsive force while maximizing there attractive force with nuclei
the lowest point on the graph represent the bond energy and the distance
