Expanded Octets In Lewis Structures
Which of the following correctly applies the concept of an expanded octet in a Lewis structure?
TABLE: Atoms Capable of Expanded Octets
| Element | Expanded Octet Capability |
|---|---|
| Phosphorus | Yes |
| Sulfur | Yes |
| Carbon | No |
A
Identifying SF6, where sulfur forms six bonds and accommodates 12 electrons, as an example of an expanded octet.
B
Representing H2O with an expanded octet on oxygen even though oxygen is limited to 8 electrons.
C
Drawing CH4, where carbon is incorrectly shown to expand its valence shell beyond 8 electrons.
D
Depicting BF3, which actually demonstrates an incomplete octet rather than an expanded octet.
