Chemical Bonding and Molecular Structure

Assertion : \(\mathrm{BO}_3^{-3}\) and \(\mathrm{SO}_3^{-2}\) are not isostructural. Reason : In \(\mathrm{SO}_3^{2-}\) sulphur has one lone pair of electron.

Which is least soluble?

Which of the following, number of lone pair at central atom zero \(\mathrm{XeO}_3, \mathrm{XeO}_2 \mathrm{~F}_2, \mathrm{XeO}_4, \mathrm{XeO}_3 \mathrm{~F}_2, \mathrm{XeF}_6\) ?

Assertion (A) Among the two \(\mathrm{O}-\mathrm{H}\) bonds in \(\mathrm{H}_2 \mathrm{O}\) molecule, the energy required to break the first \(\mathrm{O}-\mathrm{H}\) bond and the other \(\mathrm{O}-\mathrm{H}\) bond is same.
Reason (R) This...
