    In a polar molecule, the ionic charge is \[4.8\times {{10}^{-10}}\] e. s. u. If the inter ionic distance is one \[\overset{\text{o}}{\mathop{\text{A}}}\,\]unit, then the dipole moment is

    A)  41.8 debye    

    B)        4.18 debye        

    C)         4.8 debye      

    D)         0.48 debye

    Correct Answer: C

    Solution :

    Given ionic charge \[=4.8\times {{10}^{-10}}\] e. s. u. and ionic distance \[=1\,\overset{\text{o}}{\mathop{\text{A}}}\,={{10}^{-10}}\,\text{cm}\text{.}\] We know that dipole moment = ionic charge \[\times \] ionic distance \[=(4.8\times {{10}^{-10}})\times {{10}^{-8}}\] \[=4.8\times {{10}^{-18}}\,\]e. s. u per cm \[=4.8\,\text{debye}\text{.}\]
