Question

The product obtained on reaction of chloroethane with hydrogen over palladium is __________.

• A. $C_3{H}_S$
  
• B. $C_4{H}_{10}$
  
• C. $C_2{H}_6$
  
• D. $C_2{H}_4$

Answer 1

The correct option is C $C_2{H}_6$


${\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{Cl}\left(g\right)+H_2\left(g\right)\underset{}{\overset{\mathrm{Pd}/C}{\to }}{\mathrm{CH}}_3-{\mathrm{CH}}_3\left(g\right)+\mathrm{HCl}\left(g\right)\mathrm{chloroethane}\mathrm{hydrogen}\mathrm{ethane}\mathrm{hydrogen}\mathrm{chloride}$

The above reaction is a substitution reaction, where the chlorine atom in chloroethane is replaced by a hydrogen atom.

As a result ethane and hydrogen chloride are formed. This reaction is used for the preparation of pure alkanes.
