प्रश्न
Explain why is OH group in phenols more strongly held as compared to OH group in alcohols.
उत्तर
In phenol, oxygen atom is attached to sp2-hybridised carbon atom while in alcohol, it is attached to sp3-hybridised carbon atom. The bond formed between oxygen and sp2-hybridised carbon is more strongly held then that formed between oxygen and sp3-hybridised carbon.
