E cell for VO+2 is +1.00 volt and for iron its +0.77. since e cell for VO is more so its redues so E cell is 1-0.77=0.23 which is less than 0.3 so not happening
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?

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
View attachment 63567
THE ONES BELOW ARE BOTH CIS AND MIRROR IMAGES OF EACH OTHER...THE LINE IN BETWEEN IS THE MIRROR
THIS KIND OF ISOMERISM IS ONLY POSSIBLE WHEN BIDENTATE LIGANDS ARE ALSO PRESENT

1-How am I supposed to know the splitting patterns without the NMR spectrum given?
2-In column 1 is it the number of hydrogen on adjacent carbon or the carbon which is under study?
