NTA Abhyas JEE Main2020ChemistryAlcohols Phenols and EthersPractice
Which one of the following statements is not correct?
Options
- AThe bond angle in methanol is 1 0 8 . 9 o
- BAlcohols are weaker acids than water
- CCarbon-oxygen bond length in methanol, CH 3 OH is shorter than that of C - O bond length in phenol.
- DAcid strength of alcohols decreases in the following order RCH 2 OH > R 2 CHOH > R 3 COH
Correct answer
C. Carbon-oxygen bond length in methanol, CH 3 OH is shorter than that of C - O bond length in phenol.
Step-by-step solution
Carbon-oxygen bond length in methanol, CH 3 OH is longer than that of C - O bond length in phenol. This is due to the partial double bond character in C-O bond of Phenol due to resonance.
