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

`C_2H_5Cl`

`C_2H_5CHO`

`C_2H_6`

`C_2H_5OH`

Text Solution

Verified by Experts

The correct Answer is:

Ethanol reacts with hot cone. `H_S0_4` to produce ethne which decolourises bromine water and alkaline `KMn0_4` . 1 mole of ethene reacts with 1 mole of `H_2` gas to produce ethane.
