Which of the following statements is incorrect?

Which of the following statements is incorrect?

Options

  1. ACOCO is used as a reducing agent
  2. BTl(III)Tl ( III ) salts undergo disproportionation
  3. CCO2{CO}_{2} is a greenhouse gas
  4. DSiO2{SiO}_{2} is a covalent solid

Correct answer

B. Tl(III)Tl ( III ) salts undergo disproportionation

Step-by-step solution

For& TlTl , due to inert pair effect, +3+ 3oxidation state is less stable and~Tl3+{Tl}^{3 +} gets reduced to Tl1+{Tl}^{1 +}. So it does not get disproportionated, rather get reduced.
