1.	An aldehyde (A) (C_11H_8O) , which does not undergo self aldol condensation, gives benzaldehyde and two moles of (B) on ozonolysis.Compound (B), on oxidation with silver ion, gives oxalic acid. Identify the compounds (A) and (B).
Answer» Solution :Since, the given aldehyde does not undergo self aldol condensation, it will not CONTAIN `alpha`-HYDROGEN atom. Further it undergos ozonolysis indicating the presence of UNSATURATION probably at two places as the PRODUCTS are benzaldehyde and two MOLES of (B). So, the structure of given aldehyde `(C_11H_8O)` is.
