Question:

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R

Assertion (A) : Phenol reacts with \(CH_3I\) in presence of NaOH to form methoxybenzene. 

Reason (R) : Phenoxide is better nucleophile than phenol.

In the light of the above statements, choose the correct answer from the options given below

The Correct Option is A

Solution and Explanation

As the phenoxide ion $\left( C _{6} H _{5}- O ^{-}\right)$is a better nucleophile than phenol $\left( C _{6} H _{5}- OH \right)$, it reacts with $CH _{3}I$ in presence of $NaOH$ to form methoxybenzene.

Alcohols, Phenols, and Ethers

Alcohol is formed when a saturated carbon atom bonds to a hydroxyl (-OH) group. It is an organic compound that contains a hydroxyl functional group attached to a carbon atom.

Phenol is formed when the -OH group replaces the hydrogen atom in benzene. It is an organic compound in which a hydroxyl group directly attaches to an aromatic hydrocarbon.

Ether is formed when oxygen atom bonds to two alkyl or aryl groups. It is an organic compound that has an oxygen atom that is connected to two aryl and alkyl groups.
