Name the following reactions:
(i) `C_(6)H_(5)N_(2)""^(+)Cl^(-) overset(CuCl//HCl)(to) C_(6)H_(5)Cl +N_(2)`
(ii) `C_(6)H_(5)N_(2)""^(+)Cl^(-) overset(Cu//HCl)(to) C_(6)H_(5)Cl + N_(2) + Cucl`

Explanation

To solve the question, we need to identify the names of the two reactions provided. Let's analyze each reaction step by step.

### Step 1: Analyze the first reaction
The first reaction is:
\[ C_{6}H_{5}N_{2}^{+}Cl^{-} \overset{CuCl/HCl}{\rightarrow} C_{6}H_{5}Cl + N_{2} \]

1. **Identify the reactants**: The reactant is benzene diazonium chloride, \( C_{6}H_{5}N_{2}^{+}Cl^{-} \).
2. **Identify the reagents**: The reagents used are copper(I) chloride (\( CuCl \)) and hydrochloric acid (\( HCl \)).
