Problem

A valid Lewis structure of _____ cannot be drawn without violating the octet rule.

a. NF3

b. BeH2

c. SO2

d. CF4

e. SO32-

Solution

Analyze the central atom of each molecule and determine if it’s capable of having an expanded octet or an incomplete octet by constructing a Lewis structure

Step 1. Establish the octet rule exceptions

  • Recall that atoms tend to follow the octet rule which refers to the tendency of atoms to prefer eight electrons in the valence shell.
