Paragraph: Latimer diagrams show that standard reduction potentials connecting various oxidation states of an element. It shows the redox information about a series of species in a very condensed form. The latimer diagram about an element X along with its oxidation states are given below Question: Thermodynamically speaking, which of the given statement(s) is/are correct?

Options

  1. AX can disproportionate into X ⁻ and X ^ g
  2. BX can disproportionate into X ⁻ and X ⁵⁺
  3. CX ^ g ⁺ can disproportionate into X ^0 and X ⁵⁺
  4. DX ^ g ⁺ can disproportionate into X ⁻ and X ⁵⁺

Correct answer

A. X can disproportionate into X ⁻ and X ^ g
