Note the chemical reactions given below.
i) `nCH_(2)=CH-Clrarr[-CH_(2)CH-Cl]_(n)`
ii) `CH_(2)=CH_(2)+Cl_(2)rarrCH_(2)Cl-CH_(2)Cl`
iii) `CH_(3)COOH+OH-CH_(2)CH_(3)rarrCH_(3)COOCH_(2)CH_(3)+H_(2)O`
a) Identify the polymerisation reaction.
b) From the products of three reactions given, find out ethyl ethanoate.
c) Give the products of reaction if HCl is used instead of `Cl_(2)` in reaction(ii)

Explanation

a) Polymerisation reaction : Reaction No.1
b) Ethyl ethanoate: `CH_(3)COOCH_(2)CH_(3)` ( a product obtained in reaction )
c) `CH_(2)=CH_(2)+HClrarrCH_(3)CH_(2)Cl`
