A) \[NO_{2}^{-}\] and\[NH_{2}^{-}\]
B) \[NH_{2}^{-}\] and \[{{H}_{2}}O\]
C) \[NO_{2}^{-}\] and \[{{H}_{2}}O\]
D) \[B{{F}_{2}}\] and \[NO_{2}^{-}\]
Correct Answer: D
Solution :
Key Idea For \[\to \]hybridisation, there must be either \[\to \]bonds or \[\to \]bonds and one lone pair of electrons in the molecule or ions. |
\[\to \]bonds, ie, \[\to \]hybridization |
\[\to \]bonds +1 lone pair of electrons ie, \[\to \]hybridisation |
\[\to \] bonds +2 lone pairs, ie, \[\to \]hybridization |
\[\to \]bonds +2 lone pairs, ie, \[\to \]hybridization |
Thus, in \[\to \]and \[\to \]central atom is sp2 hybridised. |
