Q
Q: Which of the following is a primary amine?
Solution: CH3NH2 is a primary amine as it has one alkyl group attached to the nitrogen atom.
Steps: 6
Step 1: Understand what an amine is. An amine is a compound that contains a nitrogen atom (N) bonded to hydrogen atoms (H) and/or carbon atoms (C).
Step 2: Know the types of amines. Amines can be classified as primary, secondary, or tertiary based on how many carbon groups are attached to the nitrogen atom.
Step 3: Identify a primary amine. A primary amine has one carbon group (alkyl group) attached to the nitrogen atom, along with two hydrogen atoms.
Step 4: Look at the example CH3NH2. Here, CH3 (methyl group) is the carbon group attached to the nitrogen atom (N).
Step 5: Count the groups attached to the nitrogen in CH3NH2. There is one carbon group (CH3) and two hydrogen atoms (H).
Step 6: Conclude that since there is one carbon group and two hydrogen atoms, CH3NH2 is a primary amine.
