(iii) `C_(6)H_(5)NH_(2)+Br_(2)(aq)to`

Explanation

Let's solve the given reactions step by step:

### (i) Reaction of R-C(=O)NH₂ with LiAlH₄ in the presence of H₂O

1. **Identify the Reactants**: The reactant is an amide (R-C(=O)NH₂) and the reducing agent is lithium aluminum hydride (LiAlH₄).

2. **Reduction Reaction**: LiAlH₄ is a strong reducing agent that reduces the carbonyl group (C=O) of the amide to an alcohol and the amine group (NH₂) to an alkane.
