Select the incorrect statement

Options

  1. AIE 1 of He is greater than Ne
  2. BCl has greater election affinity than F
  3. CHClO > HClO 2 > HClO 3 > HClO 4 (order of acidity)
  4. DThere are 32 elements in period 6

Correct answer

C. HClO > HClO 2 > HClO 3 > HClO 4 (order of acidity)

Step-by-step solution

Correct acidity order is: HClO < HClO 2 < HClO 3 < HClO 4
