The correct Answer is:
To determine the classification of N-ethyl-N-methylpropan-1-amine, we can follow these steps: ### Step 1: Identify the Structure N-ethyl-N-methylpropan-1-amine consists of a propanamine backbone with ethyl and methyl groups attached to the nitrogen atom. The structure can be represented as follows: - Propan-1-amine has the formula CH3-CH2-CH(NH2)-CH3. - The nitrogen (N) in the amine is bonded to an ethyl group (C2H5) and a methyl group (CH3). ### Step 2: Determine the Type of Amine Amine classification is based on the number of carbon atoms directly bonded to the nitrogen atom: - **Primary Amine**: Nitrogen is bonded to one carbon atom. - **Secondary Amine**: Nitrogen is bonded to two carbon atoms. - **Tertiary Amine**: Nitrogen is bonded to three carbon atoms. - **Quaternary Amine**: Nitrogen is bonded to four carbon atoms. In the case of N-ethyl-N-methylpropan-1-amine, the nitrogen atom is bonded to three carbon groups (one from the propanamine backbone, one from the ethyl group, and one from the methyl group). ### Step 3: Conclusion Since the nitrogen atom is bonded to three carbon atoms, N-ethyl-N-methylpropan-1-amine is classified as a **tertiary amine**. ### Final Answer N-ethyl-N-methylpropan-1-amine is a tertiary amine. ---
