Chemical Bonding And Molecular Structure Question 415

Question: The group having triangular planar structures is:

Options:

A) $ BF_3,NF_3,CO{{_3^{2}}^{-}} $

B) $ CO_3^{2-}\text{, }NO_3^{-},SO_3 $

C) $ NH_3,SO_3,CO{{_3^{2}}^{-}} $

D) $ NCl_3,BCl_3,SO_3 $

Show Answer

Answer:

Correct Answer: B

Solution:

  • Group Hybridization Shape (1) $ BF_3 $ $ sp^{2} $ Triangular Planar (TP)

$ NF_3 $ $ sp^{3} $ Tetrahedral (T)

$ CO_3^{2-} $ $ sp^{2} $ T.P.

(2) $ . \begin{matrix} CO_3^{2-} & sp^{2} & T.P. \\ NO_3^{-} & sp^{2} & T.P. \\ SO_3 & sp^{2} & T.P. \\ \end{matrix} $

$( Allhavesame, hybridization ) $

(3) $ NH_3 $ $ sp^{3} $ T.P.

$ SO_3 $ $ sp^{2} $ T.P.

$ CO_3^{2-} $ $ sp^{2} $ T.P.

(4) $ NCl_3 $ $ sp^{3} $ T.P.

$ BCl_3 $ $ sp^{2} $ T.P.

$ SO_3 $ $ sp^{2} $ T.P.
