Question

The pair of electron in the given carbanion, CH₃C≡C⁻ , is
present in which of the following orbitals ? [2016]
(a) 2p (b) sp³
(c) sp² (d) sp

Answer 1

The pair of electron is present in sp hybridized orbital.

Option (D) is correct.

Explanation:

• The pair of electron in the CH  3 −C≡C  −   present at ≡C - carbon.
• This carbon has 1σ bond pair and two pie bonds and 11 lone pair of electrons. Thus it is sp hybridized.
• The pair of electron in the given carbanion is present in sp orbital.

Thus the pair of electron is present in sp hybridized orbital.
