MHT CET Chemistry question

Correct order of reducing power of the following carbonyl compounds.

(A)\mathrm{HCHO > CH_{3}COCH_{3} > PhCHO}
(B)\mathrm{CH_{3}COCH_{3} > PhCHO > HCHO}
(C)\mathrm{CH_{3}COCH_{3} > HCHO > PhCHO}
(D)\mathrm{HCHO > PhCHO > CH_{3}COCH_{3}}Correct

Answer: (D)

Solution

Formaldehyde is the strongest reducing agent (reduces both Tollens' and Fehling's); benzaldehyde reduces Tollens' reagent only, and acetone, a ketone,
