Question

Which of the following is closest to the C–O–C bond angle in CH3–O–CH3?
Options
A 180°
B 120°
C 109.5°
Correct Answer
D 90°
Correct Answer

Option C is the correct answer.

Detailed Explanation

In dimethyl ether (CH3-O-CH3), the oxygen is sp3 hybridized with a bent geometry. The C-O-C bond angle is approximately 109.5° (tetrahedral angle), similar to the H-O-H angle in water but slightly larger due to less lone pair repulsion.

Hint

What is the approximate tetrahedral bond angle?
