Question

1) Compounds A, B, and C have the same molecular formula: C.Hg. They all react with H2/PtO2 to give the same compound. The reaction of A or B with H2O/H2SO4 or with BH3-THF, followed by treatment with a basic solution of hydrogen peroxide, gives the same compound, namely D. The reaction of with H2O/H2SO4 also gives D. However, the reaction of C with BH3-THF, followed by HO, H202 gives a new compound, E. Provide the identity of A, B, C, D and E along with all explanations of reactivity for full credit (10 points).

Answer 1

Here in given both reaction, water is added over double bond in all three compounds and both reaction followed markonikoff's rule for addition of electrophile.
