Explanation / Answer

16) primary alcohols on oxidation alhydes are formed. Further oxidation carboxylic acids are formed.

R-CH2-OH -----[O]----> R-CHO ----[O]----> R-COOH

Hence correct option is C.Aldehyde.

17) carbonyl compounds reacts with diols or ( 2 equivalent of alcohols ) to form acetal.

Hence correct option is (B) Acetal formation

18) Huckle Rule: Aromatic compound have 4N+2 pi electrons.

Hence correct option is C) 4N+2

19)

Reactivity order of compounds towards nucleophilic acyl substitution reaction is

Thio ester ( RCOSR) < Anhydride ( R-CO-O-CO-R) < acid halide ( RCOX)

Hence compound 1. Is acid chloride more reactive

And compound 3 is thio ester is least reactive.

Hence correct option is a) 321

20)

Hydrolysis of estee in the presence of base is called as saponification reaction

Hence correct option is B) saponification
