Diethyle amine and methyle propyl amine express which type of isomers.

Options

A. functional isomers
B. position isomers
C. metamers
D. chain isomers

Answer

To determine the type of isomerism exhibited by diethylamine and methylpropylamine, we can follow these steps:

### Step 1: Understand the Structures of the Compounds
- **Diethylamine** has the structure:
\[ (C_2H_5)_2NH \]
This means it has two ethyl groups (C2H5) attached to a nitrogen atom (NH).

- **Methylpropylamine** has the structure:
\[ C_3H_7NHCH_3 \]
This means it has one methyl group (CH3) and one propyl group (C3H7) attached to a nitrogen atom.

### Step 2: Identify the Functional Groups
Both compounds contain the amine functional group (–NH). The difference lies in the alkyl groups attached to the nitrogen.

### Step 3: Analyze the Alkyl Groups
- In diethylamine, both alkyl groups are ethyl (C2H5).
- In methylpropylamine, one alkyl group is methyl (C1H5) and the other is propyl (C3H7).

### Step 4: Determine the Type of Isomerism
The difference in the alkyl groups attached to the nitrogen atom indicates that these compounds are not structural isomers in the traditional sense (like chain or position isomers). Instead, they are classified as **metamers** because they have the same functional group (amine) but differ in the structure of the alkyl groups attached to the nitrogen.

### Conclusion
Thus, diethylamine and methylpropylamine exhibit **metamerism**.

### Final Answer
The type of isomerism expressed by diethylamine and methylpropylamine is **metamerism**.
