Which is not the correct statement?

A)  The \[{{S}_{8}}\] ring is not planar

B)  Oxygen is more electronegative than sulphur

C)  \[S{{F}_{4}}\] exists, but \[O{{F}_{4}}\] does not exist

D)  \[S{{O}_{3}}\] and \[SO_{3}^{2-}\] both have trigonal planar geometry

Correct Answer: D

Solution :

\[S{{O}_{3}}\] is trigonal planar due to \[s{{p}^{2}}\]hybridised sulphur. \[SO_{3}^{2-}\] is \[s{{p}^{3}}\] hybridised but pyramidal due to lone pair of electrons.
