Which of the following structural or thermodynamic factors is NOT physically responsible for dictati — Amines Chemistry Question

💡 Solution & Explanation

The anomalous aqueous basicity of aliphatic amines is a delicate kinetic and thermodynamic balance of the +I effect (which inherently favors $3^\circ$), solvation energy (which strictly favors $1^\circ$), and steric hindrance. Statement D is completely incorrect because alkyl groups contain saturated $sp^3$ hybridized carbons and completely lack unhybridized p-orbitals to participate in resonance/delocalization with the nitrogen lone pair.
