NEETChemistryAlcohols Phenols and Ethers
Explain how does the –OH group attached to a carbon of benzene ring activate it towards electrophilic substitution?
Options
- AIn the presence of attacking electrophile, -OH group exerts +R effect on the benzene ring. So, electron densit
- BThe -OH group withdraws electron density from the benzene ring, making it more electrophilic.
- CThe -OH group forms strong covalent bonds with the benzene ring, increasing its stability.
- DThe -OH group neutralizes the benzene ring, making it less reactive towards electrophilic substitution.
Correct answer
A. In the presence of attacking electrophile, -OH group exerts +R effect on the benzene ring. So, electron densit
Step-by-step solution
Correct Option is : (A) In the presence of attacking electrophile, -OH group exerts +R effect on the benzene ring. So, electron density in the ring increases particularly at the ortho and para positions. When an electrophile attacks, substitution takes place readily at these (o and p-) positions.
