Hydrocarbons: 

Hydrocarbons Made only of carbon and hydrogen

Alkanes: 

Alkanes only single bonds CnH2n+2

Naming Alkanes: 

Naming Alkanes identify the number of carbon atoms in the longest continuous chain and use the appropriate prefix Page 187

Prefixes for Hydrocarbons: 

Prefixes for Hydrocarbons methane 1 ethane 2 propane 3 butane 4 pentane 5 hexane 6 heptane 7 octane 8 nonane 9 decane 10

The Alkanes - CnH2n+2: 

The Alkanes - CnH2n+2 CH4 - Methane 2(1) +2 = 4 C2H6 - Ethane 2(2) +2 = 6 C3HX - Propane 2(3) +2 = X C4HY - Butane Y = _______ C5HZ - Pentane Z = _______

The Alkanes - CnH2n+2: 

The Alkanes - CnH2n+2 How many hydrogen atoms are present in the six-carbon alkane? How many hydrogen atoms are present in the eight-carbon alkane?
