Vedclass · Answer

(B) $1$. In the carbanion $CH_{3}-C\equiv C^{-}$, the terminal carbon atom is bonded to another carbon atom by a triple bond.$2$. The hybridization of a carbon atom involved in a triple bond is $sp$.$3$. Since the terminal carbon atom forms one sigma bond with the adjacent carbon and holds a lone pair, its steric number is $2$ ($1$ sigma bond + $1$ lone pair).$4$. Therefore, the hybridization is $sp$, and the lone pair of electrons resides in an $sp$-hybridized orbital.

The lone pair of electrons in the given carbanion, $CH_{3}C\equiv C^{-}$, is present in which of the following orbitals?
