Which of the following statements are correct regarding the physical properties and hydrogen bonding — Amines Chemistry Question

💡 Solution & Explanation

(A) True: $1^\circ$ amines form intermolecular H-bonds, raising their BP over $3^\circ$ amines. (B) True: Soluble due to H-bonding. (C) True: While $3^\circ$ amines cannot H-bond with themselves, their nitrogen lone pair can accept a hydrogen bond from water's $O-H$, allowing lower $3^\circ$ amines to be water-soluble. (D) False: Aromatic amines like aniline possess a large hydrophobic aryl group and are insoluble in water.
