Q. An organic compound containing C, H and O gives red colouration with sodium nitroprusside solution but does not reduce Tollen’s reagent and yields chloroform on treating with $NaOH\ and\ Cl_{2}$. The compound is
A) $CH_{3}CH_{2}OH$
B) [image:12_image437.emf]
C) $CH_{3}COCH_{3}$
D) $\left( CH_{3} \right)_{2}CH - CHO$
Explanation
(c)
$CH_{3}COCH_{3}$ gives red colour with sodium nitroprusside solution but does not reduce Tollen’s reagent. Acetone yields chloroform with $NaOH/Cl_{2}$
$CH_{3}COCH_{3} + Cl_{2}\ \rightarrow Cl_{3}C - {COCH}_{3}\overset{\ \ NaOH\ \ }{\rightarrow}CHCl_{3}$
Acetone chloroform
