The compound formed when ethene reacts with hydrogen is _____ `(CH_4 , C_2H_6, C_3H_8)`

Explanation

To determine the compound formed when ethene reacts with hydrogen, we can follow these steps:

### Step 1: Identify the Reactants
The reactant in this case is ethene, which has the molecular formula \( C_2H_4 \).

### Step 2: Understand the Reaction
Ethene (an alkene) can undergo a reaction known as hydrogenation, where hydrogen gas (\( H_2 \)) is added across the double bond of the alkene. This reaction typically requires a catalyst, such as nickel, and occurs at elevated temperatures.
