From the following options :
(A) Oxidation state of Br in (\mathrm{Br}_3 \mathrm{O}_8) is
(B) Oxidation state of C in (\mathrm{C}_3 \mathrm{O}_2) is +1
(C) Oxidation state of (\mathrm{S}_{\text{in }} \mathrm{S}_4 \mathrm{O}_6{ }^{2-}) is +2.5
(D) Oxidation state of H in metal hydrides is -1
(E) Oxidation state of P in (\mathrm{P}_4) is
The correct option is:
Options
- AA, B, C, D and E one correct
- BA, C, D and E are correct
- C(\mathrm{B}, \mathrm{C}, \mathrm{D}) and E are correct
- DC and D are correct
Correct answer
D. C and D are correct
Step-by-step solution
Let's analyze each option:
- (A): Oxidation state of Br in (\mathrm{Br}_3 \mathrm{O}_8) is not . The oxidation states of Br in (\mathrm{Br}_3 \mathrm{O}_8) are +6 and +4 (not fractional).
- (B): Oxidation state of C in (\mathrm{C}_3 \mathrm{O}_2) (carbon suboxide) is not +1. It is +2.
- (C): The oxidation state of S in (\mathrm{S}_4 \mathrm{O}_6{ }^{2-}) is +2.5. This is correct.
- (D): In metal hydrides, the oxidation state of H is -1. This is correct.
- (E): The oxidation state of P in (\mathrm{P}_4) is O, not . This is incorrect.
Thus, C and D are correct.
