Vedclass · Answer

(A) Reactivity towards $HCl$ depends on the basicity of the amine. Amines act as bases by donating the lone pair of electrons on the nitrogen atom to the $H^+$ ion. Aliphatic amines are more basic than aromatic amines because the alkyl groups exert an electron-donating inductive effect ($+I$ effect), which increases the electron density on the nitrogen atom. In aqueous solution, the basicity of aliphatic amines is determined by a combination of inductive effect, solvation effect, and steric hindrance. For dimethylamine $((CH_3)_2NH)$, the combination of these factors makes it the most basic among the given options, thereby making it the most reactive towards dilute $HCl$.
