Q. Which of following reactions convert acetone into hydrocarbon having same number of carbon atoms?
A) Wolff-Kishner reaction
B) Hofmann reaction
C) Grignard reaction
D) Reduction with $LiAlH_{4}$
Explanation
(a)
$CH_{3}$
|
$CH_{3} - C = O + H_{2}N.NH_{2}\overset{- H_{2}O\ \ \ }{\rightarrow}$
$CH_{3}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ CH_{3}$
| |
$CH_{3} - C = NNH_{2}\overset{\ \ \lbrack OH\rbrack\ \ \ \ }{\rightarrow}CH_{3} - C - H$
|
$H$
propane
In Wolff-Kishner reduction carbonyl compounds are reduced to alkanes by using $NH_{2}.NH_{2}\$and $KOH$/glycol.
