Question

Phenatole can be prepared from which of the following reactants?

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

Alkylation of phenols with alkyl halides in the presence of a base is a common method to prepare ethers like phenatole.

Answer 1

The Correct Option is A

To prepare phenatole (C6H5OCH2CH3), an alkoxide group (C6H5O-) can be created by deprotonating phenol (C6H5OH) with sodium (Na). This alkoxide then reacts with an alkyl halide, ethyl bromide (CH3CH2Br), to form ethoxybenzene. Thus, the correct reactants are phenoxide (C6H5ONa) and ethyl bromide (CH3CH2Br).
