Which of the following statement(s) is/are correct?

Question

TestHub · Accepted Answer

Statement A is correct: The C–O bond orders are $CO = 3$ , $C O_{2} = 2$ , and $C O_{3}^{2 -} = 1.33$ , so $3 > 2 > 1.33$ .

Statement B is incorrect: $C r O_{5}$ has a butterfly structure with four peroxide oxygens ( $- 1$ ) and one oxo oxygen ( $- 2$ ), making the oxidation state of $C r = + 6$ .

Statement C is incorrect: The O–F bond length in $O F_{2}$ ( $\approx 1.41 \overset{˚}{A}$ ) is actually shorter than in $O_{2} F_{2}$ ( $\approx 1.57 \overset{˚}{A}$ ).

Statement D is correct: According to Bent's rule, the more electronegative equatorial F atom in $P F_{3} C l_{2}$ increases the s-character and contracts the equatorial P–Cl bonds compared to $P F_{2} C l_{3}$ .
