    The two double bonds at the interconnection between the two aryl groups and the middle portion, i.e. from aryl-CH=CH-CO-CH2-CO-CH=CH-aryl would be broken to be oxidised to both carboxylic acids ..

    Chemistry 43!!! How was it?!!

    I have drawn two alkenes instead of two ester bonds because hot concentrated KMnO4 was used to break them. And in the middle of the two aryl groups it was -C=CH-CO-CH2-CO-CH=C-
