Match the species in List I with the oxidation state of Xe in List II.
List I: P XeFX2; Q XeFX4; R XeOFX4; S XeOX4.
List II: 1 = +2; 2 = +4; 3 = +6; 4 = +8.

Answer: D
XeF2: two F at −1 gives +2. XeF4 gives +4. In XeOF4, one O (−2) and four F (−4) total −6, so Xe = +6. In XeO4, 4 O(−2) means Xe = +8.
