Which of the following is not hard base according SHAB concept?
Correct answer: D. I-
- A. NH3
- B. N2H4
- C. RNH2
- D. I-
Explanation
According to the SHAB (Soft and Hard Acids and Bases) concept, hard bases are typically small, have high charge density, and low polarizability. NH3, N2H4, and RNH2 all fit these criteria, making them hard bases. On the other hand, I- is large and highly polarizable, which classifies it as a soft base. Thus, I- is not a hard base.
