Question

Which one of the following is NOT formed when a mixture of methyl bromide and bromo benzene is heated with sodium metal in the presence of dry ether ?

• A. Ethane
• B. Diphenyl
• C. Propane
• D. Toluene

Answer 1

Answer: (C)

Propane

Answer 2

This is an example of Wurtz Fittig reaction .

$\underset{\text{methyl bromide}}{{CH_3-Br}}+2na+\underset{\text{methyl bromide}}{{Br-CH_3}} { ->[{\text{Ether}}] } \underset{\text{ethane}}{{CH_3-CH_3}}+2NaBr$

Propane cannot be prepared from this reaction .
