According to SHAB, Lewis acid are divided into
Correct answer: A. Two classes
- A. Two classes
- B. Three classes
- C. Four classes
- D. None of the above
Explanation
The SHAB (Soft Hard Acid Base) principle categorizes Lewis acids into two main classes: hard acids and soft acids. Hard acids prefer to bond with hard bases, and soft acids prefer soft bases. This classification helps in predicting and understanding the stability and reactivity of compounds. Hence, the correct answer is 'Two classes'. The other options are incorrect because they don't align with the SHAB classification of Lewis acids.
