Question

Which of the following hydrocarbons is formed when $1\text{mole}$ of hydrogen reacts with one mole of ethene in the presence of nickel catalyst?

• A. $C_2{H}_2$
• B. $C_3{H}_6$
• C. $C_2{H}_6$
• D. $C{H}_4$

Answer 1

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

The addition of hydrogen to unsaturated hydrocarbons in the presence of catalysts such as nickel lead to the formation of saturated hydrocarbons. Here, $1$ mole of ethene $\left(C_2{H}_4\right)$ reacts with $1$ mole of hydrogen in the presence of nickel catalyst to form ethane $\left(C_2{H}_6\right)$.

Hence, the correct answer is option (c).
