Which statements are correct for reagents A, B, C, and D?

Options

A. `{:(,(A),(B),(C),(D)),(a. ,H_2//Pt,MMPP,Cold alk. _4,O_2+PdCl_2),(,,,KMnO_4,+CuCl_2),(,,,,+H_2O):}`
B. `{:(,(A),(B),(C),(D)),(b. ,H_2//Pd+BaSO_4,HCO_3H,Hot alk. ,Dil. H_2SO_4),(,+qui noli n e,,KMnO_4,+Hg^(2+)):}`
C. `{:(,(A),(B),(C),(D)),(c. ,Sia_2BH,PhCO_3H,OsO_4//,O_2+PdCl_2),(,+CH_3COOH,,NaHSO_3,+CuCl_2),(,,,,+H_2O):}`
D. `{:(,(A),(B),(C),(D)), (d.,BH_3+THF,MCPBA,OsO_4//,Wacker),(,+CH_3COOH,,H_2O_2,process):}`

Answer

A, C, D

Explanation

Wacker process is used to convert alkene to carbonyl group.
`CH_2=CH_2+PdCl_2+H_2Ooverset(CuCl_2)underset(O_2)rarrCH_3CHO+Pd+2HCl`

(The reaction proceeds via the addition of `H^(o+)` and `overset(Θ)OH` by Markovnikov's rule followed by oxidation.)
