What will be the major product when m-cresol is reacted with propargyl bromide H C ≡ C - C H 2 B r in…

The $\mathrm{m}-$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 ${\mathrm{S}}_{\mathrm{N}}2$ reaction mechanism.
