Oxidation of compound A with ozone with a zinc/acid workup yielded compound B as the sole organic product, which upon reaction with one mole equivalent of ethylene glycol under acidic conditions gave compound C. Reduction of C with lithium aluminium hydride produced compound D. Compound D has a molecular formula of C9H18O3. Acid hydrolysis of compound D yields compound E. Compound E has a molecular formula of C7H14O2. Compound A decolourises a solution of Br2 in CCl4 while B, C...
