Which of the following hydrocarbons cannot be obtained by Sabatier and Senderen's reaction

A
${CH}_{4}$
B
$C_{2} H_{6}$
C
$C_{3} H_{8}$
D
All

Solution:

Methane can not be obtained by Sabatier and Senderen 's reaction because in this the product obtained contain minimum two carbon atoms.

$\begin{aligned} {CH}_{2} = {CH}_{2} + H_{2} \overset{Ni}{⟶} {CH}_{3} - {CH}_{3} \\ CH \equiv CH + 2 H_{2} \overset{Ni}{⟶} {CH}_{3} - {CH}_{3} \end{aligned}$
