Aqueous solutions of two compounds M - O - H and M' - O - H have been prepared in two different beakers. If the electronegativity of M = 3.5, M' = 1.72, O = 3.0 and H = 2.1, then the solution respectively are

Answer»

acidic , acidic
acidic , basic
basic , basic
basic , acidic

SOLUTION :In the compound M - O - H, if IE or E.N. of M is low, the compound will act as a base and if the IE or E. N. of M is high, the compound will behave as an ACID. Therefore, M - O - H will act as an acid E.N. of M is high (3.5) and M. - O - H will act as a base as E.N. of M. is low (1.72).
