Question

Name and write the structures of all isomers of the propyl and butyl alkyl groups.

Step-by-Step Solution

Answer

Isomers havingPropyl side chains are propyl and isopropyl.

Isomers having butyl side chains are butyl, isobutyl,and sec-butyl.

Step 1:Definition of Isomers

Isomers are molecules with the same chemical formula but distinct atom configurations in space.

Step 2: Structure and the IUPAC names

All isomers of the propyl, \( - {{\rm{C}}_3}{{\rm{H}}_7}\)alkyl group have the following condensed structures:

\(n - \)propyl

Iso propyl

Step 3: Structure and the IUPAC names

All isomers of the butyl, \( - {{\rm{C}}_4}{{\rm{H}}_9}\) alkyl group have the following condensed structures:

\(n - \)butyl

Iso butyl

\(\sec  - \)butyl

                             tert- butyl
