The removal of a hydrogen atom from an alkane compound creates an alkyl group. 

Types of Alkyl Groups

Concept #1: Classification of Alkyl Groups

When an alkane becomes an alkyl group the ending will change from "ane" to "yl"

The alkyl form of ethane is called ethyl. 

Propane has two alkyl forms. 

Butane has two alkyl forms. 

Isobutane is a constitutional isomer of butane and it has two alkyl forms. 

Example #1: Based on your knowledge of chemical structures draw the three isomers of C5H12 (pentane).
