Tardigrade Admin · Accepted Answer

Correct answer is (c) Carbon-oxygen bond length in methanol, CH3OH is shorter than that of C — O bond length in phenol.

Q. Which one of the following statements is not correct ?

Alcohols are weaker acids than water

Acid strength of alcohols decreases in the following order $RC H_{2} O H > R_{2} C H O H > R_{3} CO H$

Carbon-oxygen bond length in methanol, $C H_{3} O H$ is shorter than that of $C — O$ bond length in phenol.

The bond angle in methanol is $108. 9^{\circ}$

Correct answer is (c) Carbon-oxygen bond length in methanol, $C H_{3} O H$ is shorter than that of $C — O$ bond length in phenol.
