Q. Which one of the following does not have $sp^{2}$ hybridised carbon?
A) Acetone
B) Acetic acid
C) Acetonitrile
D) Acetamide
Explanation
(c)
$\ \ O$
$||$
$\ \ \ \ \ \ \ \ \ CH_{3} - C_{2} - CH_{3}$
$sp^{3}$ $sp^{2}$ $sp^{2}$
(b) $\ \ O$
$||$
$\ \ \ \ \ \ \ \ \ CH_{3} - C_{2} - OH$
$sp^{3}$ $sp^{2}$
(c) $\ \$
$\ \ \ \ \ \ \ \ \ CH_{3} - C - \equiv N$
$sp^{3}$ $sp$
(d) $\ \ O$
$||$
$\ \ \ \ \ \ \ \ \ CH_{3} - C_{2} - {NH}_{2}$
$sp^{3}$ $sp^{2}$
Acetonitrile does not contain $sp^{2}$ hybridised carbon.
