Chemical Bonding And Molecular Structure Question 142
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.
