Q: Which of the following is the correct order of basicity for the given amines?

Solution: The basicity of amines decreases with increasing alkyl substitution due to steric hindrance and electron-donating effects.

Steps: 6

Step 1: Understand that basicity refers to how well a substance can accept protons (H+).
Step 2: Recognize that amines are compounds that contain nitrogen and can act as bases.
Step 3: Identify the types of amines: primary (1 alkyl group), secondary (2 alkyl groups), and tertiary (3 alkyl groups).
Step 4: Know that as the number of alkyl groups increases, steric hindrance (crowding around the nitrogen) increases.
Step 5: Realize that more alkyl groups also mean more electron-donating effects, which can stabilize the positive charge when the amine accepts a proton.
Step 6: Conclude that the basicity decreases with more alkyl substitution due to the combined effects of steric hindrance and electron donation.
