(CHO-CHO) = R

kya hain woh? konsa waale ka?

sorry maine upar wala double bond R samja, sorry

itne gusse kyun hote hon? sorry again

J K L R are right..

not sure ? : Is S = CH2OH-COONa

:(

sodium alcohol reduces..so how -COONa

before HVZ and (T)
red P HI is also addded(1eq)

and in HVZ Br₂ is in excess so BrCH₂-COBr will be formed

oh yah!!! dat p/HI wud reduce -OH to H and then HVZ... true true....

lemme try ahead... aage lagta hai kuch Claisen hone wala hai....

BUT I had a DBT DUDE : In HVZ if its excess then first all the α-H are substituted by Br, then only wud the H of carboxylic acid be replaced,........ WAT SAY?

SO MY ANS FOR Z WUD (Br)3C-COOBr

(CH3)-(CH2)-COOH = Y

rest U V Y Z O P Q are correct..

u are right about excess HVZ...

HEY!

Y is the product formed after arndt eistert reaction of CH3-COOH then shud it not b propanoic acid as i sadi?? [7]

Oh.. in question thers Ag₂O moist also i din sae that... yeah Y is also right...

yah I know I havnt touchd upon the product I.... still thinkin [12]

It feels like pentanoic acid or sumthin but the reaction sequence doesnt suite it...

lemme [12]

dude,
wats the eq. of H2 used in converting M to N ?? [7]

M->N excess H₂/Ni

This will be the intermediate after intermol. claisen enroute frm V to W :
CH3-CO-CH2-CO-CH2-CO-OC2H5

Then on reaction with dat dibromoo comp. ??? mayb cyclisation (WILD GUESS = BLUFF) [3]

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

These are the answers done here.. rest are not solved...

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
W X and I M N...

so try these

W is wrong... :(

kk...

priyam : is I pentanoic/butanoic acid or wat?
