The one which is a representation of sec -butyl group has to be chosen from the given options. 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.
