CHM 101 Chemical Bonding and Molecular Structure Objective Question

Question

Which of the following molecules exhibits sp hybridization?
Options
A Methane (CH₄)
B Ethene (C₂H₄)
C Ethyne (C₂H₂)
Correct Answer
D Ammonia (NH₃)
Correct Answer

Option C is the correct answer.

Detailed Explanation

Ethyne (C₂H₂) exhibits sp hybridization. Each carbon atom in ethyne uses two sp hybrid orbitals to form sigma bonds (one C-H and one C-C), with the remaining two p orbitals forming two pi bonds in the triple bond, resulting in linear geometry.

Hint

Look for a molecule with triple bonds and linear geometry.
