For the Wacker process, pick the correct statement (s) from the following:
(a)Pd (II) is reduced to $\mathrm{Pd}(0)$ by $\mathrm{Cu}(\mathrm{I})$
(b)$\mathrm{Pd}(\mathrm{O})$ is oxidized to $\mathrm{Pd}(\mathrm{II})$ by $\mathrm{Cu}(\mathrm{II})$
(c)Cu(II) promotes the reductive elimination

Answer: D ✓ checked by 4AB · confidence high
The source book printed no answer; this one was worked out and checked — see the explanation.
Explanation
In the Wacker cycle Pd(II) is reduced to Pd(0) by the alkene/water step (not by Cu(I)); Cu(II) reoxidises Pd(0) to Pd(II) and is itself regenerated by O₂. Only statement B is correct.
