Unknown X, C5H9Br does not react with bromine or with dilute KMnO4 Upon treatment with potassium tert-butoxide, X gives only one product, YC5H8, Unlike X, Y decolorizes bromine and changesKMnO4 from purple to brown. Catalytic hydrogenation of Y gives methylcyclobutane. Ozonolysis-reduction of Y gives dialdehyde Z,C5H8O2 Propose consistent structures for X, Y, and Z. Is there any aspect of the structure of X that is still unknown?
