    why a is less acidic than b and d

    eduncle-logo-app

    B and D jyada Resonance stabised carbanion hai..

    eduncle-logo-app

    cross conjugation hai B and D me...

    got?

    eduncle-logo-app

    yes sir

    eduncle-logo-app

    👍

    eduncle-logo-app

    sir but extended conjugation is more stability than cross

    eduncle-logo-app

    carbanion ki stability check karo shweta...B and D me two C=O ke sath resonance me hai but A me only 1 C=O ke sath

    eduncle-logo-app

    ok sir

    eduncle-logo-app

    got it

    eduncle-logo-app

    sir ik doubt hai cross conjugation main to 3 double bond hote hai

    eduncle-logo-app

    any doubt

    eduncle-logo-app

    sir what is the step for solving such questions

    eduncle-logo-app

    first check the acidic H, Acidic H wo hota he jo EWG k pass wale carbon pr ho. then stability of Carbanion check kro

    eduncle-logo-app

    sir why a is less acidic than b and d

    eduncle-logo-app

    because yha carbocation only one C=O k sath resonance me he jbki B and D me two C=O k sath resonance krta he so less stable

    eduncle-logo-app

    B and D me cross conjunction he

    eduncle-logo-app

    ok sir

    eduncle-logo-app

    here active methylene group is present, more the EWG, more is the stability of Carbanion

    eduncle-logo-app

    abhi apn Carbanion ku baat kr rhe he to hm dekhege ki kitne EWG he
