Organic Chemistry•The chemistry of carbon compounds
•Sometimes called carbon chemistry
Organic Chemistry
•The backbone element in the molecules of all living things is carbon
Carbon Chemistry•Carbon is one of the only elements that can form long chains
•Carbon can form 4 covalent bonds
Organic Chemistry•Carbon forms covalent bonds with hydrogen, oxygen, nitrogen, phosphorus, sulfur, and the halogens
Carbon Bonding•Carbon has 4 valence electrons which can hybridize in many ways
Carbon Bonding•To determine the hybridization, draw the Lewis Dot Diagram of the carbon compound
Hybridization•sp3 4-single bonds
•sp2 2-single bonds &
1-double bond
•sp 2 doubles or T + S
Multiple Bonds•To make multiple bonds, p-orbitals are required
Hybridization•sp3 no p-orbitals
•sp2 1 p-orbital
•sp 2 p-orbitals
Single bonds & the first bond in
multiple bonds involve end-to-end
overlap:
Multiple Bonds•After the 1st bond, any others are
bonds: side-to-side p-overlap
