Question

2 chloro propane is treated with sodium in the presence of dry ether

Answer 1

It will be a wurtz reaction 
2- chloro propane  + Na + dry ether    ⇒      2,3 - dimethylbutane +  HCl

Major product obtained will be 2,3 - dimethylbutane 

Answer 2

Answer: 2,3-dimethyl-butane will formed.

Explanation:

$\text{2-chloro propane}+Na\overset{\text{dry ether}}\rightarrow \text{2,3-dimethyl-butane}$

The reaction of halo-alkane with sodium metal in presence of dry ether is known as Wurtz reaction.

When 2 chloro propane is treated with sodium in the presence of dry ether,will give 2,3-dimethyl butane as product. As shown in the image attached.
