  • question_answer
    \[{{H}_{2}}S\] is more acidic than \[{{H}_{2}}O\], due to                 [BVP  2004]

    A)                 \[O\] is more electronegative than \[S\]

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

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

    D)                 None of these

    Correct Answer: B

    Solution :

               The acidity of hydrides of VI group elements increase from top to bottom as the bond strength \[X-H\] decrease from top to bottom                                 \[{{H}_{2}}O<{{H}_{2}}S<{{H}_{2}}Se<{{H}_{2}}Te\]
