Ethyl chloride can be converted into ethane by reacting with

Chloroethane, often known as ethyl chloride, is a compound which was previously widely employed in the production of tetra ethyl lead, a gasoline additive. It is a colourless, flammable gas or liquid with a mildly pleasant odour.

Ethyl chloride to Ethane conversions can be carried out by 

$$\begin{gathered} {\mathrm{C}}_2{\mathrm{H}}_5\mathrm{Cl} \stackrel{\mathrm{Zn}+\mathrm{HCl}}{\to } {\mathrm{C}}_2{\mathrm{H}}_6 \\ {\mathrm{C}}_2{\mathrm{H}}_5\mathrm{Cl} \stackrel{{\mathrm{LiAlH}}_4}{\to } {\mathrm{C}}_2{\mathrm{H}}_6 \\ {\mathrm{C}}_2{\mathrm{H}}_5\mathrm{Cl} \stackrel{{\mathrm{H}}_2/\mathrm{Ni}}{\to } {\mathrm{C}}_2{\mathrm{H}}_6 \end{gathered}$$
