Official Correct Choice:
Option A: \( \text{sp}^3 \)
Concept:

Hybridization depends on the steric number (number of sigma bonds + lone pairs).

Solution:

  • Alkanes are saturated hydrocarbons.


  • Every carbon atom in an alkane forms exactly four single (sigma) bonds with adjacent carbon or hydrogen atoms.


  • A carbon forming 4 sigma bonds requires 4 hybrid orbitals, which are formed by mixing one s and three p orbitals.


  • This is \( \text{sp}^3 \) hybridization.


Why other options are incorrect:

sp² requires a double bond, and sp requires a triple bond. Alkanes possess neither.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
