What are the chemical structure of me сиз сиз (excess] following musing compocents Brz. mono substituted MAHAA 2 G3 77 excess KM 12 छाट reduction E2 Reduction (mild pond) NaBH3 CH 3 Mg Br HLOH H E3 HOW Hyle. bor. Holt aid. H3 oxymer/ demo. H2 Three compounds A, B, and C all have the formula C6H10. All three compounds rapidly decolorize bromine in CC14; all three are soluble in cold concentrated sulfuric acid. Compound A has an absorption in its IR spectrum at about 3300 cm, but compounds B and C do not. Compounds A and B both yield hexane when they are treated with excess hydrogen in the presence of a platinum catalyst. Under these conditions C absorbs only one molar equivalent of hydrogen and gives a product with the formula C6H12. When A is oxidized with hot basic potassium permanganate and the resulting solution acidified, the only organic product that can be isolated is CH3(CH2) 3CO₂H. Similar oxidation of B gives only CH3CH2CO₂H, and similar treatment of C gives only HO₂C(CH2)…

Give the structures of A to E, showing the absolute stereochemistry in each case.
