NEET Chemistry Properties of Phenols MCQ Question
What is the bond length of the carbon-oxygen bond in phenol, and how does it compare to that in methanol?
136 pm, which is shorter than in methanol due to partial double bond character.
136 pm, which is longer than in methanol due to partial double bond character.
140 pm, which is shorter than in methanol due to the sp2 hybridized carbon.
140 pm, which is longer than in methanol due to the sp2 hybridized carbon.
Correct Answer
Detailed Explanation
The carbon-oxygen bond length in phenol is 136 pm, which is shorter than in methanol. This is due to the partial double bond character from conjugation with the aromatic ring and the sp2 hybridized state of the carbon.
