Options

  1. A1, 2, 3 correct
  2. B2, 3, 4 correct
  3. C1, 2, 4 correct
  4. D1, 3, 4 correct

Correct answer

A. 1, 2, 3 correct

Step-by-step solution

C l 2 O and C l O 2 both gases are used to prepare N a C l O 2 , which is used as bleaching agent. B r O 3 - + F 2 + 2 O H - → B r O 4 - + 2 F - + H 2 O
