Question

Electrophilic substitution reaction in phenol take place at :

• A. p-position
• B. m-position
• C. o-position
• D. o- and p-position

Answer 1

The correct option is D o- and p-position

From the resonance structures of alcohol, we can see that the electron density at ortho and para positions will be higher than the electron density at meta position. That means $-OH$ is an ortho-para directing group towards an electrophile (electron loving species).
Hence, electrophilic substitution reaction in phenol takes place at ortho and para position.
The answer is option (d)
