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

Hybridization of carbon depends on the number of sigma bonds it forms. Four sigma bonds result in sp³ hybridization.

Solution:

  • Alkanes are saturated hydrocarbons, meaning every carbon atom is bonded to four other atoms entirely via single (sigma) bonds.


  • The mixing of one s-orbital and three p-orbitals generates four equivalent sp³ hybrid orbitals, arranged tetrahedrally.


  • Therefore, every carbon in an alkane is sp³ hybridized.


Why other options are incorrect:

sp² is found in alkenes (one double bond). sp is found in alkynes (one triple bond).

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.
