The compound 2,6-dimethyl-N,N-dimethylaniline is a substantially stronger base than simple N,N-dimet — Amines Chemistry Question

💡 Solution & Explanation

Severe steric clash between the ortho methyl groups and the N-methyl groups forces the bulky $-N(CH_3)_2$ moiety to twist completely out of the benzene ring's plane (Steric Inhibition of Resonance). This prevents lone pair delocalization, heavily localizing electron density on nitrogen.
