The role of copper salt as co-catalyst in Wacker process is
(a)oxidation of $\mathrm{Pd}(0)$ by $\mathrm{Cu}(\mathrm{II})$
(b)oxidation of $\mathrm{Pd}(0)$ by $\mathrm{Cu}(\mathrm{I})$
(c)oxidation of Pd (II) by Cu (I)
(d)oxidation of Pd (II) by Cu (II)
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
In the Wacker process Cu(II) reoxidises the Pd(0) formed after acetaldehyde release back to Pd(II); the Cu(I) produced is reoxidised by O₂.
