Practice Problem: Site of Protonation on a Weak Base

The video tutorial explains the reaction of acetamide, a weak base, with hydrochloric acid, a strong acid. It covers the Bronsted-Lowry acid-base theory, focusing on proton transfer. The tutorial discusses potential protonation sites on the acetamide molecule, emphasizing the role of lone pairs on nitrogen and oxygen atoms. It concludes with an analysis of resonance stabilization, highlighting why protonation occurs at the carbonyl position due to increased stability.
