An organic compound A of molecular formula `C_(2)H_(4)` on reduction gives another compound B of molecular formula `C_(2)H_(6)`. B on reaction with chlorine in the presence of sunlight gives C of molecular formula `C_(2)H_(5)Cl`.
(a) name the compound A,B and C
(b) Write chemical equation for the conversion of A to B and name the type of reaction.

Text Solution

Verified by Experts

The compound 'A' of molecular formula `C_(2)H_(4)` is a alkene. Upon reduction with hydrogen, it gives 'B' of molecular formula `C_(2)H_(6)`. The compound 'B' upon chlorination gives 'C' of molecular formula `C_(2)H_(5)Cl`.
(a) `underset((A)" Ethene")(CH_(2)=CH_(2))" "underset((B)" Ethane")(CH_(3)CH_(3))" "underset((C)" Chloroethane")(CH_(3)CH_(2)Cl)`
(b) `underset("Ethene (A)")(CH_(2)=CH_(2))+H_(2)underset(573K)overset(Ni)toCH_(3)-underset("Ethane (B)")(CH_(3))`
the reaction is called additon reaction.
