Question

how to convert methane into ethane

Answer 1

Explanation:

Methane to Ethane

Step 1 ; Methane reacts with chlorine gas under the ultraviolet light to give chloro-methane.

$CH_4+Cl_2\overset{h\nu}\rightarrow CH_3Cl+HCl$

Step 2 : Treat chloro-methane with sodium metal with dry ether which will give ethane as a product.

$2CH_3Cl+2Na\overset{\text{dry ether}}\rightarrow C_2H_6+2NaCl$
