    Which of the following gives correct arrangement of compounds involved based on their bond strength?

    A) \[HF>HCl>HBr>HI\]

    B)  \[HI>HBr>HCl>HF\]

    C)  \[HF>HBr>HCl>HI\]

    D)  \[HCl>HF>HBr>HI\]

    Correct Answer: A

    Solution :

                     Key Idea:\[Bond\text{ }strength\propto \frac{1}{size\text{ }of\,is\text{ }ha\log en}\] \[\because \]size of F is smallest \[\therefore \]based on bond strength \[HF>HCl>HBr>HI\]
