Which of the following is correct?
- A The number of electrons present in the valence shell of \(\mathrm{S}\) in \(\mathrm{SF}_6\) is 12
- B The rates of ionic reactions are very slow
- C According to VSEPR theory, \(\mathrm{SnCl}_2\) is a linear molecule
- D The correct order of ability to form ionic compounds among \(\mathrm{Na}^{+}, \mathrm{Mg}^{2+}\) and \(\mathrm{Al}^{3+}\) is \(\mathrm{Al}^{3+}>\mathrm{Mg}^{2+}>\mathrm{Na}^{+}\)
Answer & Solution
Correct Answer
(A) The number of electrons present in the valence shell of \(\mathrm{S}\) in \(\mathrm{SF}_6\) is 12
Step-by-step Solution
Detailed explanation
\(\mathrm{SF}_6\) does not obey octet rule as in it S-atom has 12 electrons in its valence shell.
