    structure II is correct

    eduncle-logo-app

    why sir

    eduncle-logo-app

    because S is less EN atom and behaves as electrophile while F- is a nucleophile so attack on S

    eduncle-logo-app

    sir, if 'F' is replaced by 'H' then which structure is correct?

    eduncle-logo-app

    No, you can't directly approach this. it depends on what is the reagent given with S4N4.

    eduncle-logo-app

    these reactions are possible

    eduncle-logo-app

    yes H will add on N if we take H2 with S4N4

    2nd one is correct

    eduncle-logo-app

    why

    eduncle-logo-app

    Here for nitrogen 3 bonds plus one lone pair is satisfied in 2nd one

    eduncle-logo-app

    So F attach at S and satisfy 4 bonds with sulphur too

    eduncle-logo-app

    Also you see here F and N both are more Electronegative ans S is less electronegative...so F attach with S effectively

    eduncle-logo-app

    got this?

    eduncle-logo-app

    yes

    eduncle-logo-app

    thank you
