Question

What is the approximate pKb range for aliphatic amines?
Options
A 3.0 - 4.0
Correct Answer
B 4.74 (same as ammonia)
C 8.5 - 9.5
D 10 - 12
Correct Answer

Option A is the correct answer.

Detailed Explanation

Aliphatic amines have pKb values around 3-4, making them stronger bases than ammonia (pKb = 4.74). Aromatic amines have pKb around 8.5-9.5 (weaker).

Hint

Lower pKb = stronger base.
