How is ethanol obtained from ethene?

Explanation

To obtain ethanol from ethene, we can follow a series of chemical reactions. Here’s a step-by-step breakdown of the process:

### Step 1: Identify the Reactants
- Ethene (C2H4) is the starting material. Its structure is represented as CH2=CH2.
- We need to add water (H2O) to ethene to form ethanol.

### Step 2: Protonation of Ethene
- Ethene is treated with an acid (such as HCl). The double bond in ethene is nucleophilic and can react with the electrophile (H+) from the acid.
