Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:

The oxy acid(s) of S having\[SS\]bond are/is (1)\[{{H}_{2}}{{S}_{2}}{{O}_{3}}\]                             (2)\[{{H}_{2}}{{S}_{2}}{{O}_{4}}\] (3) \[{{H}_{2}}{{S}_{2}}{{O}_{7}}\]            (4)\[{{H}_{2}}{{S}_{2}}{{O}_{6}}\]

A)  1, 2 and 3 are correct

B)  1 and 2 are correct

C)   2 and 4 are correct

D)  1 and 3 are correct

Correct Answer: C

Solution :

                  (1)                    (2) (3)         (4) Thus,\[{{H}_{2}}{{S}_{2}}{{O}_{4}}\]and\[{{H}_{2}}{{S}_{2}}{{O}_{4}}\]have\[SS\] bond.
