Practice question · True or false
A double bond counts as two electron domains when predicting molecular geometry.
Hints
- A domain is a region of electron density, not a count of pairs.
- Both pairs of a double bond occupy the same region between the same two atoms.
Show the answer
False
Why
False, a double bond is a single domain because its electrons all lie in one region between the same two nuclei. This is why CO2, with two double bonds, is linear rather than tetrahedral.
