CHM 101 Chemical Bonding and Molecular Structure Objective Question

Question

What is the bond angle associated with sp² hybrid orbitals?
Options
A 90°
B 109.5°
C 120°
Correct Answer
D 180°
Correct Answer

Option C is the correct answer.

Detailed Explanation

sp² hybrid orbitals have a bond angle of 120°. This geometry is trigonal planar, resulting from the mixing of one s orbital and two p orbitals. Examples include ethene (C₂H₄) and boron trichloride (BCl₃).

Hint

Trigonal planar geometry has three bonds equally spaced in a plane.
