A) Alcohols are weaker acids than water
B) Acid strength of alcohols decreases in the following \[RC{{H}_{2}}>{{R}_{2}}CHOH>{{R}_{3}}COH\]
C) Carbon-oxygen bond length in methanol, \[C{{H}_{3}}OH\] is shorter than that of C - O bond length in phenol.
D)
The bond angle 
in methanol is \[108.9{}^\circ \].
Correct Answer: C
Solution :
The C - O bond length in alcohols is 142 pm and in Phenol it is 136 pm. The C - O bond length in phenol is shorter than that in methanol due to the conjugation of unshared pair of electrons on oxygen with the ring, which imparts double bond character to the C ? O bond.
