Solution: Suppose a particular AB3 molecule has the resonance structureDoes this structure follow the octet rule?

Problem

Suppose a particular AB3 molecule has the resonance structure

A has a pair of dots below, and is single bonded left and right to B, which each have three pairs of dots, and double bonded above to B, which has two pairs.


Does this structure follow the octet rule?

Solution

We are asked if the given structure follows the octet rule:

A has a pair of dots below, and is single bonded left and right to B, which each have three pairs of dots, and double bonded above to B, which has two pairs.


Recall that the octet rule states that an element is surrounded by eight electrons in the Lewis structure.
