Write the equations for the following and name the products formed.

(i) Ethyl alcohol reacts with sulphuric acid at 170°C.

(ii) Acetic acid reacts with conc. sodium hydroxide solution.

(iii) Acetic acid reacts with potassium hydrogen carbonate.

(i) Products formed — ethene and water.

$\underset{\text{ ethyl alcohol}}{\text{C}$2\text{H}5\text{OH}} \xrightarrow[170\degree\text{C}]{\text{Conc. H}2\text{SO}4\text{[excess]}} \underset{ \text{ethene}}{\text{C}2\text{H}4} ↑ + \text{H}_2\text{O}\

(ii) Products formed — sodium acetate and water

CH₃COOH + NaOH ⟶ CH₃COONa + H₂O

(iii) Products formed are potassium acetate, water and carbon dioxide gas.

CH₃COOH + KHCO₃ ⟶ CH₃COOK + H₂O + CO₂ ↑
