    Same concept as you done in previous query

    eduncle-logo-app

    give Resonace first preference than hyperconjugation

    eduncle-logo-app

    2nd has allylic and benzyllic FR so more stable

    eduncle-logo-app

    yes sir but

    eduncle-logo-app

    in case of 3 and 5

    eduncle-logo-app

    benzyllic free radical in 3rd

    eduncle-logo-app

    with 2 alpha hydrogen

    eduncle-logo-app

    got now??

    eduncle-logo-app

    benzyllic free radical is more stable than allylic free radical

    eduncle-logo-app

    4 has no resonance

    eduncle-logo-app

    so least stable only hyperconjugation is there

    eduncle-logo-app

    2 ,3 ,5, 1,4

    eduncle-logo-app

    sir is this the order

    eduncle-logo-app

    2 1 3 5 4...

    eduncle-logo-app

    see in 1st benzyllic and allylic both is present

    eduncle-logo-app

    It is less stable than 2 as no alpha hydrogen in 1st but in 2nd 3 alpha hydrogen is also present

    eduncle-logo-app

    yes sir this 1st compound is my doubt

    eduncle-logo-app
