Questions & Step-by-Step Solutions
Which of the following compounds is a secondary amine?
Step 1: Understand what an amine is. An amine is a compound that contains a nitrogen atom (N) bonded to carbon atoms (C).
Step 2: Know the types of amines. There are three types: primary amines (one carbon group attached to nitrogen), secondary amines (two carbon groups attached to nitrogen), and tertiary amines (three carbon groups attached to nitrogen).
Step 3: Look at the given compound, CH3-CH2-NH-CH3. Identify the nitrogen atom (N) in the structure.
Step 4: Count the carbon groups attached to the nitrogen. In CH3-CH2-NH-CH3, there are two carbon groups: one from CH3- (methyl group) and one from CH2- (ethyl group).
Step 5: Since there are two carbon groups attached to the nitrogen, this means the compound is a secondary amine.
