Textbook Problem

Give an acceptable alternate name for each of the following branched-chain alkyl groups.

  1. a. Isopropyl group
  2. b. tert-Butyl group
  3. c. (1-Methylpropyl) group
  4. d. (2-Methylpropyl) group

(a)

Interpretation Introduction

Interpretation:

Acceptable alternate name for the given branched-chain alkyl groups has to be given.

Concept Introduction:

Alkyl groups are named according to IUPAC nomenclature.  The name is obtained considering the parent alkane name and replacing “-ane” with “-yl”.  In naming branched chain alkyl groups, this becomes little complicated.  Hence, IUPAC system for giving name to such larger groups names them by considering as if they were themselves a separate compound.  Three rules are followed while naming the larger groups.

Rule 1:

Longest continuous chain which begins at the point of attachment of the alkyl group becomes the base name for the alkyl group.

Rule 2:

Base chain that is identified is numbered in a way beginning at the point of attachment.

Rule 3:

The substituents that are present in the base chain is listed in alphabetical order using the locant as prefixes whenever necessary.

Explanation

Given branched alkyl group isopropyl,

The isopropyl group is drawn as shown above.  The bold red colored bond is the point of attachment.  The alternate acceptable name for the given isopropyl group can be given following IUPAC nomenclature...
