Consider the following elements with their electronegativity value: {:("Element",A,B,C,D),("Electronegativity (Pauling scale)",3.77,1.12,2.25,3.10):} Q. Incorrect statements is:

Answer»

AOH is more ACIDIC than DOH
BOH is more basic than COH
AB' molecule is predominantly ionic
D-OH' bond is more weaker than 'B-OH' bond in polar SOLVENT

Solution :Bont energy is INVERSELY PROPORTIONAL to differnce of ELECTRONEGATIVITY in polar solvent. Hence, `'B-OH'` is more basic 'D-OH'.
