[Holmes]

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

Great shot

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

 

[Zaki ali asghar]

This one too.

 

[anastasia grey113]

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

 

[Zaki ali asghar]

Only when MN04- is hot and concentrated?

 

[anastasia grey113]

This one too.

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.

yes
the way it is for breaking down alkenes

cis trans is only in planar ones?

 

[anastasia grey113]

cis trans is only in planar ones?

yh

 

[haithsoul]

cis trans is only in planar ones?

or octahedral

 

[anastasia grey113]

or octahedral

lol m worried abt bio tomorrow so cant focus here atm xD
u taking bio too haithsoul ?

 

[Fardeen3342]

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

 

[Zaki ali asghar]

tysm!

 

[anastasia grey113]

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

[Zaki ali asghar]

Why is the 2nd one not feasible?

 

[haithsoul]

yeah and mechanics. Idk man bio should be easy unless some weird shit comes.

 

[anastasia grey113]

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

oh my
4 subs?

more +ve - less +ve? or just add them?
