Aqueous solutions of two compounds M1 – O – H and M2 – O – H are prepared in two different beakers. If, the electronegativity of M1 = 3.4, M2 = 1.2, O = 3.5 and H = 2.1, then the nature of two solutions will be respectively:
A
Acidic, basic
B
Acidic, acidic
C
Basic, acidic
D
Basic, basic.
Answer
Acidic, basic
Explanation
Solution
The electronegativity difference between M1 and O is 0.1, which indicates M1 — O bond will be covalent. Since O—H bond have more ionic character thus bond will break and H+ ions will release and thus acidic solution is formed. The difference between electronegativity of M2 — O bond is 2.3, which will indicate that the M2 — OH bond will break and thus, the solution will be basic in nature.
