ClNO2 ( N is the central atom) Draw all the molecules by placing atoms on the grid and connecting them with bonds. Include all hydrogen atoms and all lone pairs of electrons.

Question

Draw resonance structures for each of the following molecules or ions.

Answer 1

We cannot easily draw on this platform (short of using the video recording), so I'll describe how to draw the Lewis structure the best I can.

Cl has 7 valence electrons

N has 5 valence electrons

O has 6 valence electrons x 2 = 12 valence electrons

Total valence electrons = 24

Place N in the center and attach 1 Cl and 2 O atoms (this requires a total of 6 valence electrons)

Place 3 lone pairs of electrons around the Cl and both O atoms. This requires 18 more valence electrons.

You have now used all 24 valence electrons. However the central N atom does not satisfy the octet rule.

Move 1 lone pair from either O atom and make a double bond with the N. This will be the Lewis structure.

A resonance structure will be the same as the above, only use 1 lone pair of electrons from the OTHER O atom to make the double bond.
