Answer 1

The compound which is not formed when a mixture of n-butyl bromide and ethyl bromide treated with sodium metal in the presence of dry ether is ethane.

Explanation:

Ethane cannot be produced when sodium metal is used to treat a mixture of n-butyl and ethyl bromide in the presence of dry ether because the reaction follows the Wurtz- Fittig reaction. This kind of coupling response exists.
