Depict Lewis structures of the four molecules and/or ions with the formulas given below and figure out which two of these are isoelectronic with each another. Species which are isoelectronic have the same number of atoms, the same total number of electrons, the same number of valence electrons, and the same valence electron structure (single and multiple bonds and lone pairs in same places), however need not have the same distribution of formal charges on atoms.
CN- and Cl2 andN2 and OCl-
a) CN-and N2 are isoelectronic.b) N2and Cl2 is isoelectronic.c) OCl-and Cl2 are isoelectronic.d) CN-and OCl- are isoelectronic.e) N2and OCl- is isoelectronic.
