NEET 2016 Phase 1 · ChemistryHybridisationPrevious Year Question

The lone pair of electrons in the given carbanion, , is present in which of the following orbitals?

Answer: (D) . \textbf{Answer:} (D) \textbf{Solution:} The terminal carbanion carbon has 1 sigma bond, is part of a triple bond (2 pi bonds), and carries 1 lone pair.

  1. A.
  2. B.
  3. C.
  4. D.✓

Correct Answer

(D)

Solution & Explanation

\textbf{Answer:} (D) \textbf{Solution:} The terminal carbanion carbon has 1 sigma bond, is part of a triple bond (2 pi bonds), and carries 1 lone pair. With two regions of electron density (one sigma + the lone pair), it is hybridized, so the lone pair resides in an orbital.
