Question

Name the type of isomerism exhibited by the following pairs of compound
(1) $(C_2{H}_5{)}_{2}NH$ and $C{H}_3-NH-C_3{H}_7$
(2) $1-butanol$ and $2$ methyl$-1-$ propanol

Answer 1

(1) $(C_2{H}_5{)}_{2}NH$ and $C{H}_3-NH-C_3{H}_7$ shows metamerism. They differ in the nature of alkyl group attached to N atom.
(2) 1−butanol and 2 methyl−1− propanol show chain isomerism. They differ in the carbon skeleton / alkyl chain. One is straight chain (1-butanol) and other is branched (2 methyl−1− propanol).
