What is the major product Y in the following reaction sequence?




The sequence first involves diazotization of aniline to form a diazonium salt.
Hydrolysis gives phenol, which undergoes Williamson ether synthesis to give anisole.
Bromination of anisole in acetic acid selectively yields para-bromoanisole as the major product.
Consider the following sequence of reactions : 
Molar mass of the product formed (A) is ______ g mol\(^{-1}\).
Predict the major product $ P $ in the following sequence of reactions:
(i) HBr, benzoyl peroxide
(ii) KCN
(iii) Na(Hg), $C_{2}H_{5}OH$
