Why positive charge stable on small ring and negative charge stable on larger ring?

negative charge stabilisation

positive charge stabiisation

And please tell in what respect you are asking this...Means you stuck on any ques or something else??

yes sir this one.

okk wait sourav

sourav is it option A??

yes

dear sourav you know this ease of release H+ more more acidic

Smaller rings have more -I effect more EN character...so it will make more acidic

so 3rd is most acidic here...

Now come to I and II...as in both cyclohexane ring is present...but also In 1st Oxygen is there which is also electronegative...so overall we see here Acidity order 3>1>2

But in general when you talk...then positive charge is stablised by higher rings as lower rings have more -I character so it destabilises the positive charge

Read this two article which i send here...there are various factors which stabilises and destabilizes positive and negative charge

but sir then what about this. it says five membered ring cation receives more stability than 6 member ring.

but here by protonation we check na...and here we check for acidity that where H+ releases easily...so thats why we consider here na electronegativity factor....

just you think na....you know smaller membered rings have more -I effect...so how positive charge is stabilised in ring

and five membered heterocyclic ring is more stable it has more aromatic property than six membered heterocyclic ring because of the heteroatom.

In this there is always competency which is more stable 😊

and when we talking simply no heteroatom then 6 membered cyclo hexane is more stable than 5 membered...chair conformation

This you know what i 'm explaining...so in doing problems you have to differentiate these and write these things as a note...if you go by taking general concept only not with some exceptions then it creates problem sourav

ok only for heteroatomic ring 5 member more stable than 6.
