In acetylene (C2H2), hybridzation of carbon atoms is:

Show answer & explanation

Correct answer: C

Explanation

The correct answer is  option 3  i.e.  sp.

In acetylene (C₂H₂), each carbon atom is sp-hybridized.

  • Each carbon forms two sigma bonds: one with the other carbon and one with a hydrogen atom.

  • To form these two sigma bonds, each carbon uses one s orbital and one p orbital to create two sp hybrid orbitals.

  • The remaining two unhybridized p orbitals on each carbon form two pi bonds between the carbons, creating a triple bond.

Hybridization of carbon atoms in acetylene is sp.
