    \[{{H}_{2}}S\] is more acidic than \[{{H}_{2}}O\] because

    A)  \[O-H\] bond is stronger than \[S-H\] bond

    B)  \[O\] is more electronegative than sulphur

    C)  \[H-S\] bond is weaker than \[O-H\] bond

    D)  \[O-H\] bond is weaker than \[H-S\] bond

    Correct Answer: C

    Solution :

    H-S bond is weaker than 0-H bond because S-atom is bigger in size and less electronegative than 0-atom. Due to these reason \[{{H}_{2}}S\] is more acidic than \[{{H}_{2}}O\].
