Which is an incorrect statement?

Options

  1. ADiamond is unaffected by conc. acids, but graphite reacts with hot conc. H N O 3 forming mellitic acid C 6 ( C
  2. BC O is toxic because it forms a complex with hemoglobin in the blood
  3. CC 3 O 2 , carbon suboxide, is a foul-smelling gas
  4. DC O C l 2 is called tear gas.

Correct answer

D. C O C l 2 is called tear gas.

Step-by-step solution

C O C l 2 is phosgene gas and tear gas is phenacyl chloride.
