A) It can acts as bidentate ligand
B) Two N-N bond lengths are different in the anion.
C) It is isoelectronic and isostructural with \[C{{O}_{2}}\]
D) There are two \[\sigma \] and three \[\pi \] bonds.
Correct Answer: C
Solution :
[a] Four membered ring is not stable. |
[b] Both N-N bond lengths are identical and that is 1.15 |
[c] \[N_{3}^{-}\] and both\[C{{O}_{2}}\] have same number of electrons i.e. 22; so isoelectronic. |
\[{{N}^{-}}=\underset{sp}{\mathop{\overset{+}{\mathop{N}}\,}}\,={{N}^{-}}\](linear) \[O=\underset{sp}{\mathop{C}}\,=O\](linear) |
So, both are also isostructural |
[d] There are two and two bonds. |
