Which out of the following has the highest boiling point ?
`(i) C_(2)H_(5)OH " "(ii) C_(2)H_(5)Br" "(iii) CH_(3)OH`
`(iv) C_(3)H_(6)" " (v) CH_(3)OCH_(3). `

Explanation

To determine which compound has the highest boiling point among the given options, we need to consider the factors that influence boiling points, such as molecular weight and the ability to form hydrogen bonds.

### Step-by-Step Solution:

1. **Identify the Compounds and Their Molecular Weights:**
- (i) Ethanol (C₂H₅OH): Molecular weight = 46 g/mol
- (ii) Ethyl bromide (C₂H₅Br): Molecular weight = 109.96 g/mol
- (iii) Methanol (CH₃OH): Molecular weight = 32 g/mol
