Which of the following is correct?

Question

Which of the following is correct? (A) The number of electrons present in the valence shell of textS in SF6 is 12 (B) The rates of reactions involving ionic compounds are very slow. (C) According to VSEPR theory SnCl2 is a linear molecule (D) The correct order of ability to form ionic compounds among Na+,Mg2 + and Al3 + is Al3 +>Mg2 +>Na+

Tardigrade Admin · Accepted Answer

In SF6 molecule, there are six bond pairs thus sulphur has 12 valence electrons. Rest other statements are incorrect as ionic reactions are fast, SnCl2 is bent and the ability to formed ionic compound is Al3 + < Mg2 + < Na+ .

Q. Which of the following is correct?

The number of electrons present in the valence shell of $S$ in $S F_{6}$ is 12

The rates of reactions involving ionic compounds are very slow.

According to VSEPR theory $S n C l_{2}$ is a linear molecule

The correct order of ability to form ionic compounds among $N a^{+}, M g^{2 +}$ and $A l^{3 +}$ is $A l^{3 +} > M g^{2 +} > N a^{+}$

In $S F_{6}$ molecule, there are six bond pairs thus sulphur has 12 valence electrons. Rest other statements are incorrect as ionic reactions are fast, $S n C l_{2}$ is bent and the ability to formed ionic compound is $A l^{3 +} < M g^{2 +} < N a^{+}$ .
