Which of the following statements for rubredoxin,A. $\mathrm{F_2^{+}}$ center has a tetrahedral geometry.B. Reduced form of iron is diamagnetic.C. $\mathrm{F_2^{+}}$ center undergoes Jahn-Teller distortion.D. It is a [2Fe–2S] cluster.are correct?
(a)A, B and C
(b)A, C and D
(c)C and D only
(d)A and C only
Answer
Answer: D ✓ checked by 4AB · confidence medium
Explanation
Rubredoxin has a single Fe in a tetrahedral Cys₄ site, not a 2Fe–2S cluster. Reduced high-spin Fe(II) is paramagnetic, and the tetrahedral d⁶ e³t₂³ ion shows a Jahn–Teller distortion. A and C only (d).
