An organic liquid A containing C,H and O...

An organic liquid `A` containing `C,H` and `O` has a pleasant odour with a boiling point of `78^(@)C`. On boiling. A with conc. `H_(2)SO_(4)` a colourless gas is produced which decolourises bromine water and alkaline `KMnO_(4)`. One mole of this gas also takes one mole of `H_(2)`. The organic liquid `A` is

A

`C_(2)H_(5)Cl`

B

`C_(2)H_(5)CO OCH_3`

C

`C_2H_5 OH`

D

`C_2 H_6`

Text Solution

Verified by Experts
