Vedclass · Answer

(A) Option $A$ is correct because in $SF_6$,the sulfur atom forms $6$ covalent bonds with $6$ fluorine atoms,resulting in $12$ electrons in its valence shell,which violates the octet rule.Option $B$ is incorrect because ionic reactions occur almost instantaneously due to the presence of free ions in solution.Option $C$ is incorrect because $SnCl_2$ has a bent geometry due to the presence of one lone pair on the $Sn$ atom.Option $D$ is incorrect because according to Fajan's rule,the ability to form ionic compounds decreases as the charge density increases. Thus,the correct order of ionic character is $Na^{+} > Mg^{2+} > Al^{3+}$.
