Chemical Bonding And Molecular Structure Question 301

Question: In which of the following molecules/ions $ BF_3 $ , $ N{O^{-}}_2 $

$ N{H^{-}}2 $ , and $ H_2O $ the central atom is $ sp^2{} $ hybridized-

Options:

A) $ BF_3 $ and $ N{O^{-}}_2 $

B) $ N{O^{-}}_2 $ and $ N{H^{-}}_2 $

C) $ N{H^{-}}_2 $ and $ H_2O $

D) $ N{O^{-}}_2 $ and $ H_2O $

Show Answer

Answer:

Correct Answer: A

Solution:

  • Molecule hybridisation
    $ BF_3 $ $ sp^{2} $
    $ N{O^{-}}_2 $ $ sp^{2} $
    $ NH_2^{-} $ $ sp^{3} $
    $ H_2O $ $ sp^{3} $

$ \Rightarrow BF_3 $ and $ NO_2^{-} $ are $ sp^{2} $ hybridized. Hance, option (1) is correct.
