Please solve this problem

oxalic acid is more acidic than malonic acid which is more acidic than succinic acid

No electron releasing methyl group in oxalic acid...one in malonic acid and 2 in succinic acid

sir how to solve this kind of questions

check for aromatic and antiaromatic system

stability of aromatic >non aromatic >antiaromatic

So if reaction leads to instability then it is not possible

sir here no cyclic ring is present and has no planarity how aromatic ka concert kasa lagega

cyclic ring to hai na...4 membered first me hai..cyclobutadiene...4 pi electrons antiaromatic

last me dekho...3 membered ring or conjugation bhi hai double bond or negative charge...so 4 pi electrons...antiaromatic

mujhe sir kuch v samaj nhi aa raha mujhe toh sir yaha acyclic compound he dikh raha hai

sorry shib i m explaining another ques explanation

sorry sorry

This is previous ques explanation

ok sir no problem now please solve this problem😊

Here you easily solve shib...methyl group electron releasing grp increase hone se acidity kam hota hai

oxalic acid me ek bhi methyl grp nhi hai....

sir i thought i should form anion between the two cooh grps and check the anion stability

yes this also you can check in case of malonic acid and succinic acid...active methylene grp hai malonic ke case me

so malonic jyada acidic hai succinic acid se kyunki carbanion stabilised honge two EWG se

but sir usaa mai oxalic acid ko kaha rakhu samaj nhi aa raha tha so

yha only cooh grp ..releasing nature to nhi hai na methyl ka...or carboxylate ion jyada stabilised hai or sabhi se

shib check all other queries too
