Concept explainers
(a)
Interpretation:
The “complex” five-carbon branched alkyl group has to be named using IUPAC rules.
Concept Introduction:
Alkyl groups are named according to
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 are listed in alphabetical order using the locant as prefixes whenever necessary.
(b)
Interpretation:
The “complex” five-carbon branched alkyl group has to be named using IUPAC rules.
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 are listed in alphabetical order using the locant as prefixes whenever necessary.
