three compounds A,B and C all have the formula C5H8. All three compounds will decolorize bromine in CCl4. Compound A reacts with NaNH2. Compounds A and B both yield pentane when they are treated with excess H2 with the pt catalyst. Under the same conditions C absorbs only 1 mol of H2 and gives the product C5H10. Reaction of compound B ozone at 78deg followed by Zn workup gives three different compounds, one of which is a formaldehyde. Reaction of C with ozone gives only one compound, a symmetrical dialdehyde with the formula C5H8O2. What are the structures of A,B and C?
