Find the longest chain which contains carboxylic acid.
Numbering is done from the carboxylic acid group.
a) longest chain has 5 carbon , so parent name pentane.
There is two methyl group at 3 and 4 position.
IUPAC name : 3,4-dimethylpentanoic acid
b) longest chain have 4 carbons, so parent name butane
At position 2 there is a amino group
IUPAC name : 2-aminobutanoic acid
c)
Longest chain has 6 carbons, so parent name hexane
IUPAC name: hexanoic acid
