Chapter A, Problem A.7P

Interpretation Introduction

(a)

Interpretation:

IUPAC name for the molecule is to be written.

Concept introduction:

In the IUPAC nomenclature, the longest continuous carbon chain is considered as the parent chain. The name of this corresponding parent chain will be the root of the molecule’s name. For naming straight chain alkyl substituents, begin with the name of the straight-chain alkane that has the same number of carbon atoms as the alkyl substituent and replace the ‘ane’ suffix with ‘yl’. For naming the branched substituents,

identify the longest continuous chain of carbons in the alkyl group beginning at the substituent’s point of attachment. This establishes the main chain of the branched alkyl group. Number the carbon atoms of the branched alkyl group’s main chain with $\text{C1}$ being the atom at the point of attachment. The root name of the branched alkyl substituent is named in the same way as the straight chain alkyl substituent. Add prefixes and locants that account for the alkyl groups attached to the parent chain. Enclose the entire name of a branched alkyl group in parentheses.

(b)

Interpretation:

IUPAC name for the molecule is to be written.

Concept introduction:

In the IUPAC nomenclature, the longest continuous carbon chain is considered as the parent chain. The name of this corresponding parent chain will be the root of the molecule’s name. In case of two or more different substituents, the alphabetical order is considered. For naming straight chain alkyl substituents, begin with the name of the straight-chain alkane that has the same number of carbon atoms as the alkyl substituent and replace the ‘ane’ suffix with ‘yl’. For naming the branched substituents,

identify the longest continuous chain of carbons in the alkyl group, beginning atthe substituent’s point of attachment. This establishes the main chain of thebranched alkyl group. Number the carbon atoms of the branched alkyl group’s main chain with $\text{C1}$ being the atom at the point of attachment. The root name of the branched alkyl substituent is named in the same way as the straight chain alkyl substituent. Add prefixes and locants that account for the alkyl groups attached to the parent chain. Enclose the entire name of a branched alkyl group in parentheses.
