A hydrocarbon (X) with vapour density = ...

A hydrocarbon (X) with vapour density = 27 containing C = 88.88% decolourizes `KMnO_(4)` and `Br_(2)` water without evolving HBr. It gave no ppt. with ethereal ammonical `AgNO_(3)` or `Cu_(2)CI_(2)` When reacted with dil. `H_(2)SO_(4)` in the presence of mercuric sulphate, methyl ethyl ketone (Y) is formed.
The compound is

A

`C_(8)H_(12)`

B

`C_(4)H_(6)`

C

`C_(2)H_(3)`

D

`C_(5)H_(10)`

Text Solution

Verified by Experts

The correct Answer is:
B
Based on the percentages (88.88% C and 11,12% H) its emphirical formula `C_(2)H_(3)` `MW = 2 xx 27 = 54 , MF = C_(4)H_(6)`
