Hope I helped u.

Answer 2

Answer: The compound 'A' is 1-bromo-2,2-dimethyl propane

Explanation:

We are given a chemical reaction, that follows:

$A+2Na\xrightarrow[]{\text{Dry ether}}\text{2,2,5,5-Tetra methylhexane}+2NaBr$

When two molecules of alkyl halide is treated with sodium metal in the presence of dry ether, it leads to the formation of alkane. This reaction is known as Wurtz reaction.

In this reaction, the alkane formed will have double the number of carbon atoms as compared to the carbon atoms in parent alkyl halide.

Hence, the compound 'A' is 1-bromo-2,2-dimethyl propane
