1. Alkanes

2. Homologous Series Homo (same) logous
a series of organic compounds having the same functional group but with each successive member differing by CH2,
molecular formula - the actual number of
atoms of each element in a molecule,

3. Alkanes The classic example is the alkanes CH4 C2H6
General formula - the simplest algebraic
formula of a member of a homologous series, ie for an alkane: CnH2n + 2,

4. Alkanes are saturated hydrocarbons
Straight chain hydrocarbons
A carbon chain – the number of carbons connected by C-C bonds

5. Alkanes
You need to know the first 10

6. Shapes
VSEPR so …………
