    I dont think this is the case. It would still show optical isomerism.

    Why would HO2CCO2H react with MN04- ions? and which reaction is this?

    just like HCOOH is further oxidised to CO2 by KMnO4, similarly, HOOCCOOH is also oxidised

    Only when MN04- is hot and concentrated?

    well the first one shows both: optical due to bidentates and cis trans because there are pairs of two types of ligands.
    the 2nd one shows only cis trans since its square planar
    the 3rd one shows neither becuz the shape is tetrahedral so no cis trans and secondly not all the ligands are different so optical cant be shown either

    ethnadioc acid will be oxidised by any stron oxidising agent like MNO4 to carbon dioxide and water. Also methanoic acid.

    well the two cis shown are optical isomers or mirror images of each other

    add together the E values of both the reactions of VO2+ and Fe3+ in the data booklet
    if answer is -ve reaction is not feasible
