Observe the following species (i) \(\mathrm{NH}_3\) (ii) \(\mathrm{AlCl}_3\) (iii) \(\mathrm{SnCl}_4\) (iv) \(\mathrm{CO}_2\) (v) \(\mathrm{Ag}^{+}\) (vi) \(\mathrm{HSO}_4^{-}\)
How many of the above species act as Lewis acids?
- A 5
- B 3
- C 4
- D 2
Answer & Solution
Correct Answer
(C) 4
Step-by-step Solution
Detailed explanation
\(\mathrm{O}=\mathrm{C}=\mathrm{O}\) electron deficiency due to attraction of more electronegative atom oxygen. \(\mathrm{AlCl}_3\) electron deficient Al \(\mathrm{Ag}^{+}\)electron deficient \(\mathrm{SnCl}_4\), Sn electron deficient Thus 4 species act as Lewis acid.
