Based on the previous question about Step 2 (Ethene to Ethane) and common organic reaction pathways, I will assume the following reaction scheme to answer the questions, as the full diagram was not provided:

• Step 1: Ethanol $\rightarrow$ Ethene
• Step 2: Ethene $\rightarrow$ Ethane
• Step 3: Ethene $\rightarrow$ Ethanol
• Step 4: Ethene $\rightarrow$ 1,2-Dibromoethane (or similar addition product)
• Step 7: Ethene $\rightarrow$ Poly(ethene) (Compound D)

(ii) Write an equation for the reaction that takes place in:

Step 1: Write the equation for the dehydration of ethanol to ethene.

$$\text{CH}_3\text{CH}_2\text{OH(l)} \xrightarrow{\text{conc. H}_2\text{SO}_4, 170^\circ\text{C}} \text{CH}_2=\text{CH}_2\text{(g)} + \text{H}_2\text{O(l)}$$

Step 2: Write the equation for the hydration of ethene to ethanol.
