A student is told to name the arrangement that includes every electron pair around the central atom. That name is the:
AEmpirical formula
BStructural isomer
CMolecular structure
DElectron-pair geometry
Answer & Solution
Correct answer: D. Electron-pair geometry
1. Both bonding pairs and lone pairs are counted in it.
2. The other name would count only the atoms.
3. It is the electron-pair geometry.
