Q. Identify the correct sequence of increasing number of a bonds in the structures of the following molecules: I. $ {{H}_{2}}{{S}_{2}}{{O}_{6}} $ II. $ {{H}_{2}}S{{O}_{3}} $ III. $ {{H}_{2}}{{S}_{2}}{{O}_{5}} $
EAMCETEAMCET 2004Chemical Bonding and Molecular Structure
Solution:
Structure of $ {{\text{H}}_{\text{2}}}\text{S}{{\text{O}}_{\text{3}}} $ is
So, the correct order of increasing number of bonds is II, III, I
