Question

Which of these is true regarding reduction of carboxylic acids and their derivatives? Sodium borohydride will reduce carboxylic acids to alcohols Lithium aluminum hydride will reduce esters and amides to alcohols Lithium aluminum hydride will reduce esters and acid chlorides to primary alcohols LiAIH(1BuO)3 will reduce carboxylic acids to aldehydes, but not to alcohols Why are amines basic, but amides are not basic? Amides can delocalize the positive charge through resonance while amines can't Amines have more conformational flexibility Amides are more polar than amines The amide lone pair is conjugated with the carbonyl Which of these is true about using amines in SN2 reactions? Primary, secondary, and tertiary amines can all act as the nucleophile in an SN2 reaction Tertiary amines won't undergo SN2 reactions because of steric hindrance Amines are nucleophilic enough to react with even tertiary alkyl halides in an SN2 reaction Aromatic amines such as aniline will not react in S*2 reactions
