JEE Main 2026 — 4 April, Evening Shift — Question 55

The electronegativity of a group 13 element ' E ' is same as that of Ge (on Pauling scale and upto one decimal point). The CORRECT statements about E3+\mathrm{E}^{3+} are A. It can act as a reducing agent. B. It can act as an oxidizing agent. C. E3+\mathrm{E}^{3+} is more stable than E+\mathrm{E}^{+}. D. The standard electrode potential value for E3+/E\mathrm{E}^{3+} / \mathrm{E} is positive. Choose the correct answer from the options given below

  1. Option A:

    A and C Only

  2. Option B:

    B and C Only

  3. Option C:

    B and D Only

    Correct
  4. Option D:

    A and D Only

Answer: C

Step-by-step solution

. EN of ' Tℓ\mathrm{T} \ell ' is 1.8 that is same as 'Ge' ' E ' =Tℓ=\mathrm{T} \ell Tℓ+3\mathrm{T} \ell^{+3} acts as oxidizing agent Stability order : Tℓ+3<Tℓ+1\mathrm{T} \ell^{+3}<\mathrm{T} \ell^{+1} (due to inert pair effect) The standard electrode potential value E∘(Tℓ3+/Tℓ)\mathrm{E}^{\circ}\left(\mathrm{T} \ell^{3+} / \mathrm{T} \ell\right) =+1.26 V=+1.26 \mathrm{~V}
