Verified step by step guidance

Identify the structure given: \(\mathrm{CH_3CH_3NH}\). This notation seems ambiguous, so clarify the structure by considering the possible arrangement of the groups around the nitrogen atom in the amine.
Recall that amines are named based on the alkyl groups attached to the nitrogen atom. The simplest amines are primary (one alkyl group), secondary (two alkyl groups), and tertiary (three alkyl groups).
Analyze the groups attached to the nitrogen: if the nitrogen is bonded to two methyl groups (\(\mathrm{CH_3}\)) and one hydrogen, the amine is a secondary amine called dimethylamine.
If the nitrogen is bonded to one ethyl group (\(\mathrm{CH_2CH_3}\)) and two hydrogens, the amine is ethylamine, a primary amine.
If the nitrogen is bonded to three methyl groups, it is trimethylamine, a tertiary amine. Based on the structure, determine which alkyl groups are attached to nitrogen to select the correct common name.
