The reaction \( \boldsymbol{C} \boldsymbol{H}_{2}=\boldsymbol{C} \boldsymbol{H}_{2}+ \) \( \boldsymbol{H}_{2} \underbrace{\frac{N i}{250-300^{\circ}}} \boldsymbol{C} \boldsymbol{H}_{3}-\boldsymbol{C H}_{3} \) is called

1. Wurtz reaction
2. Kolbe's reaction
3. Sabatier - Sendern's reaction
4. Cabylamine reaction

Correct answer: Sabatier - Sendern's reaction

Solution

The reaction shown adds hydrogen across the double bond of ethene in the presence of nickel at 250–300°C, converting it to ethane. That catalytic hydrogenation is known as the Sabatier–Senderens reaction.
