    answer 2 is correct due to in both conditions they have 18π electrons

  • Tejas

    to check isoelectronic coordination complex ..we check only valence electron..?? is this correct?

    option 2 [Pd(pph3)4] and [Ni(CO)4 ] both have sp3 hybridisation so tetrahedral structure so isostructual both have same electrons i.e., 18e so isoelectronic

    option B Both A and F has sp3 hybridization (tetrahedral)and total electrons=18

    here we check valence electron...?can we consider total electron.. ??

    eduncle-logo-app

    valence or better you say effective atomic number

    eduncle-logo-app

    if we consider total electron than option 3 complexes also isoelectronic... ??

    eduncle-logo-app

    consider valence electrons
