Write the equation involved in the following reactions :
(i) Wolff-Kishner reductin (ii) Etard reaction

Explanation

To write the equations for the Wolff-Kishner reduction and the Etard reaction, we will break down each reaction step by step.

### (i) Wolff-Kishner Reduction

**Step 1: Identify the reactants**
- The Wolff-Kishner reduction typically involves a carbonyl compound, such as acetophenone (C6H5COCH3), and hydrazine (N2H4) in the presence of a strong base like potassium hydroxide (KOH) and heat.

**Step 2: Write the reaction**
