Step-by-step solution
(A) Diethylamine ( CH₃CH₂-NH-CH₂CH₃ ) and Methyl propylamine ( CH₃-NH-CH₂CH₂CH₃ ) have different alkyl groups attached to the polyvalent -NH- group. They exhibit metamerism. (A IV) (B) Butan-1-ol and Butan-2-ol differ only in the position of the -OH group on the main carbon chain. They exhibit position isomerism. (B II) (C) Pentane (a straight chain) and Isopentane (a branched chain) differ in their carbon skeletons. They exhibit chain isomerism. (C I) (D) Propanone is a ketone and Propanal is an aldehyde.
