Write the chemical equations involeved in the following reactions:
(i) Hoffmann-bromamide degradation reaction
(ii) Carbylamine reaction

Explanation

### Step-by-Step Solution

#### (i) Hoffmann-bromamide Degradation Reaction

1. **Starting Material**: The reaction begins with a primary amide, which can be represented as \( RCONH_2 \). For example, let's consider ethanamide (acetamide) as our amide, which is \( CH_3C(=O)NH_2 \).

2. **Reagents**: The reagents used in this reaction are bromine (\( Br_2 \)) and sodium hydroxide (\( NaOH \)). The sodium hydroxide is typically used in excess.
