An organic compound A containing C, H and O has a pleasant odour with boiling point of 78 ° C . On boiling A with concentrateed H 2 S O 4 , a colourless gas is produced which decolourises bromine water and alkaline K M n O 4 . The organic liquid A is

Options

  1. AC 2 H 5 C l
  2. BC 2 H 5 C O O C H 3
  3. CC 2 H 5 O H
  4. DC 2 H 6

Correct answer

C. C 2 H 5 O H

Step-by-step solution

The organic liquid A is C 2 H 5 O H . (i) Ethyl alcohol is a colourless liquid with a characteristic pleasant smell, having boiling point 78.1 ° C . (ii) C 2 H 5 OH → conc .   H 2 SO 4 CH 2   =   CH 2 Decolourises   Br 2   water     and   alkaline   KMnO 4
