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

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

 

[anastasia grey113]

Only when MN04- is hot and concentrated?

yes
the way it is for breaking down alkenes

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

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

Why is the 2nd one not feasible?

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

 

[anastasia grey113]

Why is the 2nd one not feasible?

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?

 

[anastasia grey113]

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

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.

 

[haithsoul]

oh my
4 subs?

what does subs mean? lol

 

[anastasia grey113]

what does subs mean? lol

u took 4 subjects?

 

[haithsoul]

u took 4 subjects?

yes yes

 

[anastasia grey113]

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?

 

[anastasia grey113]

yes yes

wowww MA
