Arrange the following in decreasing order of solubility in water:
`(CH_(3))_(3)N, (CH_(3))_(2)NH, CH_(3)NH_(2)`

Explanation

To determine the decreasing order of solubility in water for the compounds `(CH₃)₃N`, `(CH₃)₂NH`, and `CH₃NH₂`, we need to analyze their ability to form hydrogen bonds with water. Here’s a step-by-step solution:

### Step 1: Identify the Compounds
The compounds we need to analyze are:
1. Trimethylamine: `(CH₃)₃N`
2. Dimethylamine: `(CH₃)₂NH`
3. Methylamine: `CH₃NH₂`
