Q. An organic compound of molecular formula $C_{3}H_{6}O$ did not give a silver mirror with Tollen’s reagent, but gave an oxime with hydroxylamine, it may be

A) $CH_{3} - CO - CH_{3}$
B) $C_{2}H_{5}CHO$
C) $CH_{2} = CH - CH_{2} - OH$
D) $CH_{3} - O - CH = CH_{2}$
Explanation

(a)
Organic compound gave an oxime with hydroxyl amine, therefore, it must be an aldehyde or ketone.
Organic compound did not give silver mirror with Tollen’s reagent, therefore, it cannot be an aldehyde.
Therefore, compound is ketone and its molecular formulae with be $CH_{3}COCH_{3}$.
