What will be the major product when m-cresol is reacted with propargyl bromide H C ≡ C - C H 2 B r in presence of K 2 C O 3 in acetone?

Correct answer

1

Step-by-step solution

The m - cresol is the m-methyl phenol. Phenol is acidic in nature. It gives the acid-base reaction with base. So, when it reacts with the base, it will form the phenolate ion. After that phenolate ion act as a nucleophile. This nucleophile gives the nucleophilic substitution reaction with the alkyl halide. It will follow the S N 2 reaction mechanism.
