Question:

Among the following sets of reaction which one produces anisole?

C6H5−CH3;CH3COCl;AlCl3

CH3CHO;RMgX

C6H5OH;neutralFeCl3

C6H5OH;NaOH,CH3I

Solution:

Among the following sets of reaction, the reaction C6H5OH;NaOH,CH3I produces anisole. This is because phenol (C6H5OH) reacts with sodium hydroxide (NaOH) to form sodium phenoxide. The sodium phenoxide then undergoes a Williamson ether synthesis reaction with methyl iodide (CH3I) to produce anisole (methoxybenzene, C6H5OCH3). The other options do not lead to the formation of anisole.
