-1- 1. Circle the choice or choices within the brackets which complete the below statements correctly. (20 points) The Hell-Volhard-Zelinski reaction describes the [ carbonation of organometallics with CO 2 / the formation of amides from ammonium carboxyla tes at high temperatures / the reaction phthalimide salts with alkyl halides to give primary amines (after hydrolysis) / the α -bromination of carboxylic acids with Br 2 and P ]. The Mannich reaction is essentially an aldol reaction in which the electrophile is [ an aldehyde / an iminium salt / a nitrile / NO + / AgO ]. Diethylamine is a [ stronger / weaker ] base than the ethanoate anion, and a [ stronger / weaker ] acid than butyllithium. It is [ chiral / not chiral ]. An acid chloride reacts with water to give a carboxylic acid and HCl. Mechanistically, this reaction [ involves the elimination of chloride followed by the additi on of water to the C=O bond / is essentially an S N 2 process / is essentially an S N 1 process / involves a tetrahedral intermediate / is formally an oxidation
