A) \[B{{F}_{3}},N{{F}_{3}},CO{{_{3}^{2}}^{-}}\]
B) \[CO_{3}^{2-}\text{, }NO_{3}^{-},\,\,S{{O}_{3}}\]
C) \[N{{H}_{3}},S{{O}_{3}},CO{{_{3}^{2}}^{-}}\]
D) \[NC{{l}_{3}},BC{{l}_{3}},S{{O}_{3}}\]
Correct Answer: B
Solution :
| [b] Group Hybridization Shape |
| (1) \[B{{F}_{3}}\] \[s{{p}^{2}}\] Triangular Planar (TP) |
| \[N{{F}_{3}}\] \[s{{p}^{3}}\] Tetrahedral (T) |
| \[CO_{3}^{2-}\] \[s{{p}^{2}}\] T.P. |
| (2) \[\left. \begin{matrix} CO_{3}^{2-} & s{{p}^{2}} & T.P. \\ NO_{3}^{-} & s{{p}^{2}} & T.P. \\ S{{O}_{3}} & s{{p}^{2}} & T.P. \\ \end{matrix} \right\}\left( \begin{align} & \text{All}\,\,\text{have}\,\,\text{same}\, \\ & \text{hybridization} \\ \end{align} \right)\] |
| (3) \[N{{H}_{3}}\] \[s{{p}^{3}}\] T.P. |
| \[S{{O}_{3}}\] \[s{{p}^{2}}\] T.P. |
| \[CO_{3}^{2-}\] \[s{{p}^{2}}\] T.P. |
| (4) \[NC{{l}_{3}}\] \[s{{p}^{3}}\] T.P. |
| \[BC{{l}_{3}}\] \[s{{p}^{2}}\] T.P. |
| \[S{{O}_{3}}\] \[s{{p}^{2}}\] T.P. |
