Answer #1

CHYCHz MyBn (erues) Hoa) Phingeh H21109) OH CHA Mg Ba (2equin Helcor) сні The order of reactivity with grignard reagent is,

Acedic H>CHO>CO>COCl>COOR

In the first reaction, ester gives a tertiary alcohol.

In the second reaction, only one equivalent RMgX is there. Hence, alcohol H reacts with alkyl group to give alkane I.e, benzene.

In the third reaction first acid H reacts with RMgX and produces CH4. The second equivalent reacts with aldehyde to give secondary alcohol.
