MCQ
Aqueous solution of two compounds $M_1OH$ and $M_2OH$ are prepared in two different beakers if the $EN$ of $M_1 = 3.4, EN$ of $M_2 = 1.2, EN$ of $O = 3.5$ and $EN$ of $H = 2.1$, then nature of two solutions will be
  • ✓
    Acidic, Basic
  • B
    Acidic, Acidic
  • C
    Basic, Acidic
  • D
    Basic, Basic
✓

Answer

Correct option: A.
Acidic, Basic
a
$M_1 -O -H$       $M_2 -O -H$
In water, bond will be broken from that side where $\Delta EN$ is max.
