A

butane

B

octane

C

hexane

D

ethane

Text Solution

Verified by Experts

The correct Answer is:

D

When a mixture of n-butyl bromide and ethyl bromide is treated with sodium metal in the presence of dry ether, then ethane cannot be formed because reaction follows Wurts-Fittig reaction. It is a type of coupling reaction. ltBrgt `CH_(3)CH_(2)CH_(2)CH_(2)Br+CH_(3)CH_(2)Br+2Na overset("Dry")underset("ether")rarr underset("Octane")(C_(4)H_(9)-C_(4)H_(9))+underset("Hexane")(C_(4)H_(9)-C_(2)H_(5)+underset("Butane")(C_(2)H_(5)-C_(2)H_(5))`
