Draw all of the Lewis structures of NO2+ which obey the octet rule and use this Lewis structure or these resonance structures to predict how many covalent bonds connect each oxygen atom in the real structure to the central N atom. Assume that the octet rule is followed for the N atom when you draw your structure(s). Pick the correct statement from the choices below.
a) Each oxygen atom is connected to the central N atom with 2 covalent bonds.
b) Each oxygen atom is connected to the central N atom with 1 covalent bonds.
c) Each oxygen atom is connected to the central N atom with 1.33 covalent bonds.
d) Each oxygen atom is connected to the central N atom with 1.25 covalent bonds.
e) Each oxygen atom is connected to the central N atom with 1.5 covalent bonds.
