How many hydrogen atoms are available for intermolecular hydrogen bonding on the central nitrogen at — Amines Chemistry Question

💡 Solution & Explanation

N-Ethyl-N-methylaminoethane is a tertiary amine, specifically N-ethyl-N-methylethanamine (a mixed 3° amine). In a tertiary amine, the nitrogen atom is bonded exclusively to three carbon atoms and has zero hydrogen atoms directly bonded to it. Hence, it cannot act as a hydrogen bond donor.
