Question

Planar structure is shown by:

• A. $C{O}^{2-}3$
  
• B. $BC{l}_3$
  
• C. $N(Si{H}_3{)}_3$
• D. All of these

Answer 1

The correct option is D All of these



Due to backbonding in $N(Si{H}_3{)}_3$, it has planar structure.
In $BC{l}_3$; B and in $C{O}_3^{2-}$ C has $s{p}^2$ hybridisation.
