    The bond length of\[HCl\]bond is\[2.29\times {{10}^{-10}}m.\] The percentage ionic character of \[HCl\] if measured dipole moment is\[6.226\times {{10}^{-30}}C\text{-}m,\] is

    A)  8%                                        

    B)  20%                      

    C)  17%                                      

    D)  50%

    Correct Answer: C

    Solution :

    \[{{\mu }_{cal}}=e\times d=1.6\times {{10}^{-19}}\times 2.29\times {{10}^{-10}}\]      \[=3.664\times {{10}^{-29}}C\text{-}m\] % ionic character\[=\frac{{{\mu }_{\exp }}}{{{\mu }_{cal}}}\times 100\]                                                 \[=\frac{6.226\times {{10}^{-30}}}{3.664\times {{10}^{-29}}}\times 100\]                                 \[=17%\]
