Which of the following relationships correctly describe the structural isomers of a nitrogenous comp — Isomerism and Stereochemistry Chemistry Question

💡 Solution & Explanation

Diethyl amine and methyl propyl amine are $2^\circ$ amines with different alkyl distributions around the nitrogen, making them metamers. 1-Butanamine and 2-Butanamine differ only in the locant of the $-NH_2$ group, making them positional. 1-Butanamine ($1^\circ$) and N-methylpropanamine ($2^\circ$) are functional isomers. Option D is incorrect because a $3^\circ$ amine and a $1^\circ$ amine differ functionally, rendering them functional isomers, not just chain isomers.
