Consider the oxy acids H C l O n series, here value of n is 1 to 4. Then incorrect statement regarding these oxy acids is

Options

  1. AAcidic character of oxy acids increases with increasing value of n
  2. BOxidizing power of oxy acids increases with decreasing value of n
  3. CThermal stability of oxy acids decreases with increasing value of n
  4. DC l - O bond order decreases with decreasing value of n

Correct answer

C. Thermal stability of oxy acids decreases with increasing value of n

Step-by-step solution

Here statement given in option C is incorrect while rest other are correct as follows Acidic character: H O C l < H C l O 2 < H C l O 3 < H C l O 4 Oxidizing power: H O C l > H C l O 2 > H C l O 3 > H C l O 4 Thermal stability: H O C l < H C l O 2 < H C l O 3 < H C l O 4 C l - O bond order: H O C l < H C l O 2 < H C l O 3 < H C l O 4 .
