Question

Which of the following statements are correct for the compound $C_3{N}_3(N_3{)}_3$?

• A. It contains three pi bonds.
• B. Its structure is planar.
• C. C and N atoms are $s{p}^2$ hybridized in the ring.
• D. ${N_3}^{-}$ groups are attached with N-atoms.

Answer 1

The correct option is B Its structure is planar.

I) Three pi bonds are present in the ring system. There are additional pi bonds outside the ring. Hence, the statement I is incorrect.
II) The compound has ring structure. Thus, the statement II is correct.
III) Both $C$ and $N$ atoms present in the ring undergo $s{p}^2$ hybridization. Thus, the statement III is correct.
IV) $N_3^{-}$ groups are attached with ring $C$ atoms. Thus, the statement IV is incorrect.
