Alkyl Groups Practice Problems

An alkyl group with four carbons can exist in four different forms. Draw these alkyl groups to identify the degree of substitution as primary (1°), secondary (2°), or tertiary (3°), of the head carbon atom.

Draw all four different four-carbon alkyl groups and give each of them the appropriate systematic name.

Show the structures and give the common names of the following groups: (a) 2,2-dimethylpropyl, (b) 2-methylbutyl, (c) 4-methylpentyl, and (d) -(CH₂)₄CH₃.

Show the structures of (a) 1-(sec-butyl)-4-methylcycloheptane and (b) 3,4,7-trimethyl-5-propylnonane.

Provide the correct structures corresponding to the names (a) hexylcyclohexane and (b) 1-( tert-butyl)-3,5-dimethylcyclohexane.
