What is the S-O bond order? d. Draw the Lewis structure for NF3. Either way, everything has a full octet, so I don't know why putting a double-bond with one of the oxygens is considered "most reasonable". Since nitrogen is less electronegative than oxygen and chlorine, assume that the central atom is nitrogen. Now, the octet rule of nitrogen is not satisfied, and hence, we need to add a double bond between nitrogen and oxygen. Hence, nitrogen has five valence electrons, oxygen has six valence electrons, and chlorine has seven valence electrons. Draw the two electron dot resonance forms that satisfy the octet rule and that together are consistent with the fact that the two nitrogen-oxygen bonds are equivalent. Our tutors have indicated that to solve this problem you will need to apply the Bond Angles concept. Step 3: We will now find out the central atom in the molecule. Since the NO2Cl compound has two oxygen atoms attached to the nitrogen atom, two equivalent lewis structures will be necessary to describe it.
