    More resonance more single bond character...so more is the bond length...so d>b

    eduncle-logo-app

    overall order a>d>b>c

    eduncle-logo-app

    now got this....or any doubt??

    Divya keep one concept in mind...resonance increases then single bond character in double bond increases and double bond character in single bond increases

    In a it is single bond...no resonance...so maxm bond length

    eduncle-logo-app

    In c it is pure double bond...no resonance...so it least bond length

    eduncle-logo-app

    In d there is more resonance than b

    eduncle-logo-app

    sir is resonance directly proportional to bond length?

    eduncle-logo-app

    a>d>b>c

    eduncle-logo-app

    sir I understood a , c but not d, b
