Options
- AEthene can be converted into benzene by adding a methyl group to the double bond in the presence of a suitable
- BEthene can be directly converted into benzene by heating it to a high temperature in the absence of oxygen.
- CEthene was first converted into 1,2-dibromoethane by the action of bromine, tetrachloromethane. Then it is tre
- DEthene cannot be converted into benzene through any known chemical process.
Correct answer
C. Ethene was first converted into 1,2-dibromoethane by the action of bromine, tetrachloromethane. Then it is tre
Step-by-step solution
Correct Option is : (C) Ethene was first converted into 1,2-dibromoethane by the action of bromine, tetrachloromethane. Then it is treated with alc. KOH to form bromoethene which will further react with NaNH 2 /liq.NH 3 to form ethyne. After that ethyne is heated in the red-hot iron tube at 873 K, benzene is obtained.
