    shouldnt it be like 0.77-1? becuz like the E for VO2+ sure is 1.00 but in it VO2+ is being oxidised to V2+ so shouldnt it be changed to -1?

    just add them but like if a reaction is going in revers i.e. the species is being oxidised instead of being reduced, then reverse its sign.

    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

    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...

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

    Zaki ali asghar i think phenol should ionise in such a high pH aint it? and i think it is tyr that is P and the phe-tyr and phe are R and S becuz like phe has a low mass and double the charge since phenol and acid both ionise and since phe-tyr has double the mass and double the charge than tyr...

    Also Holmes this is actually the correct explanation well you can only have two isomers cis and trans and for the cis isomer, there will be two optical isomers since there is also a bidentate ligand present THIS IS TRANS THE ONES BELOW ARE BOTH CIS AND MIRROR IMAGES OF EACH OTHER...THE LINE IN...
