Arrange the following compounds in an increasing order of their acid strengths :
`(CH_(3))_(2)CHCOOH, CH_(3)CH_(2)CH(Br)COOH, CH_(3)CH(Br)CH_(2)COOH`

Explanation

To determine the increasing order of acid strengths for the compounds given, we need to analyze the structures and the effects of substituents on the carboxylic acid group (-COOH). The compounds to compare are:

1. (CH₃)₂CHCOOH (2-methylpropanoic acid)
2. CH₃CH₂CH(Br)COOH (3-bromobutanoic acid)
3. CH₃CH(Br)CH₂COOH (2-bromobutanoic acid)

### Step 1: Analyze the first compound, (CH₃)₂CHCOOH
- This compound has two methyl groups attached to the carbon adjacent to the carboxylic acid group.
