Chemistry Question from JEE Main 2026 · 24 January, Shift 1

Given below are two statements:

Statement I: The number of paramagnetic species among [CoF6]3[\mathrm{CoF_6}]^{3-}, [TiF6]3[\mathrm{TiF_6}]^{3-}, V2O5\mathrm{V_2O_5} and [Fe(CN)6]3[\mathrm{Fe(CN)_6}]^{3-} is 33.

Statement II: K4[Fe(CN)6]<K3[Fe(CN)6]<[Fe(H2O)6]SO4H2O<[Fe(H2O)6]Cl3\mathrm{K_4[Fe(CN)_6]} < \mathrm{K_3[Fe(CN)_6]} < \mathrm{[Fe(H_2O)_6]SO_4 \cdot H_2O} < \mathrm{[Fe(H_2O)_6]Cl_3} is the correct order in terms of number of unpaired electrons.

Choose the correct answer from the options given below:

  • A

    Both Statement I and Statement II are false

  • B

    Statement I is false but Statement II is true

  • C

    Statement I is true but Statement II is false
