When bromoethane is subjected to Wurtz reaction, the hydrocarbon inixture so obtained consists of

A

butane only

B

butane and ethane

C

butane and ethene

D

butane, ethane and ethene

Text Solution

Verified by Experts

The correct Answer is:
D
Butane, ethane and ethane. Butane is formed by Wurtz reaction while ethane and ethane are produced by a bimolecular elimination reaction,
`2C_2H_5Br + 2Na underset(Delta)overset("Dry ether ")to underset("Butane")(C_2H_5-C_2H_5 ) + 2NaBr `
`C_2H_5 Br + Na to C_2H_5^(-) Na^(+)`
`C_2H_5 Na^(+) + H-CH_2 - CH_2 - Br to underset("Ethane")(C_2H_6) + CH_2 = underset("Ethene")(CH_2+ NaBr)`
