Arrange the following ions in the order of decreasing X−O\mathrm{X}-\mathrm{O} bond length, where X\mathrm{X} is the central atom

Options

  1. AClO4−,SO42−,PO43−,SiO4−\mathrm{ClO}_{4}^{-}, \mathrm{SO}_{4}^{2-}, \mathrm{PO}_{4}^{3-}, \mathrm{SiO}_{4}^{-}
  2. BSiO44−,PO43−,SO42−,ClO4−\mathrm{SiO}_{4}^{4-}, \mathrm{PO}_{4}^{3-}, \mathrm{SO}_{4}^{2-}, \mathrm{ClO}_{4}^{-}
  3. CSiO44−,PO43−,ClO4−,SO42−\mathrm{SiO}_{4}^{4-}, \mathrm{PO}_{4}^{3-}, \mathrm{ClO}_{4}^{-}, \mathrm{SO}_{4}^{2-}
  4. DSiO44−,SO42−,PO43−,ClO4−\mathrm{SiO}_{4}^{4-}, \mathrm{SO}_{4}^{2-}, \mathrm{PO}_{4}^{3-}, \mathrm{ClO}_{4}^{-}

Correct answer

B. SiO44−,PO43−,SO42−,ClO4−\mathrm{SiO}_{4}^{4-}, \mathrm{PO}_{4}^{3-}, \mathrm{SO}_{4}^{2-}, \mathrm{ClO}_{4}^{-}

Step-by-step solution

More will be the electronegativity of X\mathrm{X} lesser will be the bond length of X‾−O\underline{X}-\mathrm{O} bond.
