The pair of electron in the given carbanion, $CH_3C\equiv C^-$, is present in which orbitals?
A
$sp^3$
B
$sp^2$
C
sp
D
2p
Explanation
The carbanion carbon is sp hybridised.
Detailed Solution
In $CH_3-C\equiv\ddot{C}^-$, both triple-bonded carbons are sp hybridised, so the lone pair is present in an sp orbital.
