Question

In a localized, non-resonating carbanion such as the methyl carbanion ($CH_3^-$), what is the accepted hybridization state and resultant molecular geometry of the negatively charged carbon atom?

Prashant Kotian · Accepted Answer

Correct answer: B. In a simple, localized carbanion like , the carbon atom uses three hybrid orbitals to form bonds and the fourth orbital to hold the unshared lone pair. This hybridization with one lone pair gives a distorted tetrahedral, or trigonal pyramidal, geometry.
