1.	1,4-pentadiene reacts with excess of HCI in thepresence of benzoyl peroxide to give compound X which upon reaction with excess of Mg in dry ether forms Y. Compound Y on treatment with ethyl acetate followed by dilute acid yields Z. Identify the structures of compound X,Y and Z.
Answer» SOLUTION :1,4-Pentadiene on addition with excess of HCI in the PRESENCE of benzoyl PEROXIDE, forms 2,4-dichloro pentane (X) because HCI does not SHOW peroxide effect.
