Question

An organic compound A of molecular formula C2H4 on reduction gives another compound B of molecular formula C2H6. B on reaction with chlorine in presence of sunlight gives C of molecular formula C2H5Cl. a) Name the compound A,B and C b) Write the equation for the conversion of A to B. And name the type of reaction

Answer 1

alkene is having general formula C2H4 so A is ethene
C2H4 + H2 —> C2H6
it's reduction or addition reaction as hydrogen addition take place. compound B is ethane.
C2H6 + Cl -> sunlight-< C2H5Cl
so compound C is chloroethane

Answer 2

A-Ethene
B-Ethane
C-Chloroethane

Reation - AtoB

ni/pd
C2H4+H2---------->C2H6(Addition or hydrogenation reaction)

Reaction-BtoC
-------------------------
sunlight
C2H6+Cl2---------------->C2H5Cl + HCl(substitution reaction)
