Arrange the following in increasing orde of base strength : methylamine, dimethylamine , aniline , N-methylamiline .

Explanation

To arrange the compounds methylamine, dimethylamine, aniline, and N-methyl aniline in increasing order of base strength, we can follow these steps:

### Step 1: Identify the Types of Amines
- **Methylamine (CH₃NH₂)** and **Dimethylamine (CH₃)₂NH** are aliphatic amines.
- **Aniline (C₆H₅NH₂)** is an aromatic amine.
- **N-Methyl aniline (C₆H₅N(CH₃)H)** has both an aromatic and an aliphatic component.

### Step 2: Understand Basicity in Amines
