Chemical Bonding And Molecular Structure Question 428

Question: Arrange the following ions in the order of decreasing $ ~X-O $ bond length, where X is the central atom

Options:

A) $ ClO_4^{-},SO_4^{2-},PO_4^{3-},SiO_4^{-} $

B) $ SiO_4^{4-},PO_4^{3-},SO_4^{2-},ClO_4^{-} $

C) $ SiO_4^{4-},PO_4^{3-},ClO_4^{-},SO_4^{2-} $

D) $ SiO_4^{4-},SO_4^{2-},PO_4^{3-},ClO_4^{-} $

Show Answer

Answer:

Correct Answer: B

Solution:

  • More will be the electronegativity of X, lesser will be the bond length of $ X-O $ bond.
