    Which of the following equation is used in Pauling's scale of electronegativity?

    A) \[{{x}_{A}}=0.187(IE+EA)+0.17\]

    B) \[{{x}_{A}}-{{x}_{B}}=0.182\] \[{{[{{E}_{A-B}}-\sqrt{({{E}_{A-A}}\times {{E}_{B-B}})}]}^{1/2}}\]

    C) \[{{x}_{A}}=\frac{0.359\,\,{{Z}_{eff}}}{r_{A}^{2}}+0.744\]

    D)  None of the above

    Correct Answer: B

    Solution :

    According to Pauling's scale of electro negativity. \[{{x}_{A}}-{{x}_{B}}\] \[=0.182[({{E}_{A-B}}-{{({{E}_{A-A}}\times {{E}_{B-B}})}^{1/2}}]\]
