Which of the following is correct?

Options

  1. AThe number of electrons present in the valence shell of S in SF ₆ is 12
  2. BThe rates of ionic reactions are very slow
  3. CAccording to VSEPR theory, SnCl ₂ is a linear molecule
  4. DThe correct order of ability to form ionic compounds among Na ⁺, Mg ²⁺ and Al ³⁺ is Al ³⁺> Mg ²⁺> Na ⁺

Correct answer

A. The number of electrons present in the valence shell of S in SF ₆ is 12

Step-by-step solution

SF ₆ does not obey octet rule as in it S-atom has 12 electrons in its valence shell.
