    The correct order of acidity is −COOH>NO2​−Ar−OH>Ar−OH>C≡CH.  Thus, when only 2 equivalents of soda amide are used, first, the carboxylic group will be deprotonated, then phenolic −OH group (in the ring containing nitro group ) will be deprotonated.

    no2 pehle aata I think

    eduncle-logo-app

    nhi

    eduncle-logo-app

    .....

    eduncle-logo-app

    acidity order k according hoga

    eduncle-logo-app

    NaNH2 strong base he so simply ye sbse phle more acidic H nikalega na?? or yha COOH most acidic then ArOH

    eduncle-logo-app

    ar no2 ni hai

    eduncle-logo-app

    NO2 acidic nhi he ye ArOH ki acidiy increase krta he

    eduncle-logo-app

    sir

    eduncle-logo-app

    acetylene is which group - I or + i

    eduncle-logo-app

    shweta yha pr +/- ka koi role nhi he just different functional groups de rkhe he apko acidic order yaad rkhna he

    eduncle-logo-app

    ni mujhe pta

    eduncle-logo-app

    aise for general knowledge poocha

    eduncle-logo-app

    okay

    eduncle-logo-app

    now any doubt?

    eduncle-logo-app

    Aapne btaya to hai no acetylene - I effect kyun Deta + I kyun ni

    eduncle-logo-app

    acetylene have sp hybridisation so have -I

    eduncle-logo-app

    got it shweta??

    eduncle-logo-app

    ok sir

    got this shweta ?

    eduncle-logo-app

    sir order ni pta chalta

    eduncle-logo-app

    I mean kon - I dega

    eduncle-logo-app

    kon -+ i

    eduncle-logo-app

    Acidity check krna hai phle..coo- stabilised hai Resonating structure se most acidic

    eduncle-logo-app

    No2 -I effect...to ye next acidic hoga

    eduncle-logo-app

    phenoxide ion 5 resonating structure se stabilised hai

    eduncle-logo-app

    Next alkyne

    eduncle-logo-app

    ye SB - I effect denge

    eduncle-logo-app

    So most acidic to least acidic order se remove honge...jitne moles given ho uske according

    eduncle-logo-app

    carboxylate ion two resonating structures se most resonance stabilised hai

    eduncle-logo-app

    ok

    eduncle-logo-app

    sir

    eduncle-logo-app

    acetylene is which group - I or + u

    eduncle-logo-app

    it show acidic character as it is sp hybridised 50% s character more electronegativity

    eduncle-logo-app

    resonance effect dominance hote hai inductive pe

    eduncle-logo-app

    check krna hai phle acidity ke order ko diff group ke liye....

    eduncle-logo-app

    sir

    eduncle-logo-app

    sir

    eduncle-logo-app
