Which of the following statements is incorrect?

Options

  1. ACO is used as a reducing agent
  2. BTl   ( III ) salts undergo disproportionation
  3. CCO 2 is a greenhouse gas
  4. DSiO 2 is a covalent solid

Correct answer

B. Tl   ( III ) salts undergo disproportionation

Step-by-step solution

For Tl , due to inert pair effect, + 3   oxidation state is less stable and Tl 3 + gets reduced to Tl 1 + . So it does not get disproportionated, rather get reduced.
