Two organic compound A and B both containing only carbon and hydrogen, on quanctities analysis gave the same percentage composition by weight:
`C=(12//13)xx100%, H=(1//3)xx100%`
A decoulourises bromine water but B does not. A and B respectively are

A

`C_(2)H_(2) and C_(6)H_(6)`

B

`C_(6)H_(6)and C_(2)H_(6)`

C

`C_(2)H_(4) and C_(2)H_(6)`

D

`C_(2)H_(4) and C_(2)H_(6)`

Text Solution

Verified by Experts

The correct Answer is:
A

E.f. of hydrogcarbo=CH
A is `C_(2)H_(2) and B is C_(6)H_(6)`
`underset("Acetylene")(HC)=CH+2Br to CHBr_(2)-CHBr_(2)`
`underset("Benzene")(C_(6)H_(6))+Br_(2) to "No reaction"`
