Propanamine and N,N-dimethanamine contain the same number of carbon atoms ,even though propanamine has higer boiling point than N,N- dimethymethanamine .Why?

Explanation

To understand why propanamine has a higher boiling point than N,N-dimethylamine despite both containing the same number of carbon atoms, we can analyze the structures and bonding characteristics of these compounds step by step.

### Step 1: Identify the Structures
- **Propanamine (C3H9N)**: This is a primary amine with the structure CH3-CH2-CH2-NH2. It has one nitrogen atom bonded to two hydrogen atoms and one carbon chain.
- **N,N-Dimethylamine (C3H9N)**: This is a tertiary amine with the structure (CH3)2N-CH2. It has one nitrogen atom bonded to two methyl groups (CH3) and one carbon chain.

### Step 2: Determine the Type of Amine
- **Propanamine**: Being a primary amine, it has one nitrogen atom bonded to a carbon chain and two hydrogen atoms. This allows for hydrogen bonding between the molecules.
