Question

Planar structure is shown by:

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

Answer 1

The correct option is D

All of these

The carbon in $C{O}_3^{2-}$ is $s{p}^2$ hybridised and so has a planar structure.

Due to backbonding in $BC{l}_3$ and $N(Si{H}_3{)}_3$, they are planar in structure.
