Question
What is the structure of N-ethyl-N-methyl Ethanamine ?
A CH3NHCH(CH3)2
B (CH3)2NCH2CH3
C (CH3CH2)2NCH3
D (CH3)3CNH2
Solution
The structure of N-ethyl-N-methyl Ethanamine is (CH3CH2)2NCH3. So, the correct answer is C.
Here's how you can determine this:
- The prefix 'N-ethyl-N-methyl' indicates that an ethyl (CH3CH2) and a methyl (CH3) group are attached to the nitrogen atom.
- 'Ethanamine' indicates that the main chain is an ethane (two carbons, CH3CH2) with an amine group (-NH2) attached.
- Since there are two 'N-' prefixes before 'ethanamine', it means that both the ethyl and the methyl group are attached to the nitrogen, not to the carbon chain.
- Therefore, the structure is (CH3CH2)2NCH3.
