These set of questions are assertion type: There are two statements in a sentence. Choose from the options A-E if A)Both statements are true and related B)Both statements are true but not related C)The first statement is true and the second statement is false D)The first statement is false and the second statement is true E)Both statements are false I)Quartenary ammonium salts with hydrocarbon chains are used as detergent BECAUSE the presence of hydrophobic tail and ionic head facilitates its detergent action. II)Hofmann elimination is a reaction between an unsubstituted amide and an alkaline solution of bromine BECAUSE the advantage of Hofmann rearrangement is that it yields pure primary amines III)Nitriles undergo catalytic hydrogenation or reduction with LiAlH4 to yield primary amines BECAUSE this reaction is a technique for shortening carbon chain in an amine. IV)Benzylamine synthesis from benzaldehyde follows the mechanism of reductive amination BECAUSE benzylamine is synthesised form benzaldehyde through an enamine intermediate V)Hyperconjugation can stabilise carbocation intermediates BECAUSE secbutyl carbocation can rearrange to a tertbutyl carbocation. VI)Reductive amination requires a hydrogen on the carbonyl carbon to proceed BECAUSE Reductive amination converts only aldehydes to amines VII)Pyridine is more basic than piperidine BECAUSE pyridine is resonance stabilised. VIII)Hinsberg test can distinguish between various alkyl halides BECAUSE not all alkyl halides form the benzenesulponamide product is formed from the Hinsberg reaction.
