Identify the correct order of increasing number of `pi`-bonds in structures of the following molecules.
`(I) H_(2)S_(2)O_(6) (II) H_(2)SO_(3) (III) H_(2)S_(2)O_(5)`

A

`(I),(II),(III)`

B

`(II),(III),(I)`

C

`(II),(I),(III)`

D

`(I),(III),(II)`

Text Solution

Verified by Experts

The correct Answer is:
B
`H_(2)S_(2)O_(6), H-O-underset(O) underset(||) overset(O) overset(||) S-underset(O) underset(||) overset(O)overset(||)S-OH = 4 pi - bonds`
`H_2 SO_3, HO- overset(O) overset(||)S-OH = on e pi-bond`
`H_2S_2O_5, HO-overset(O) overset(||) underset(O) underset(||)S-underset(O) underset(||) S-OH = 3 pi-bonds`.
