VSEPR quest Flashcards
naming covalent compounds
use greek prefixes
naming acids that contain oxygen
name the polyatomic ion, add -ate/-ic and add acid
- -ate to -ic
- ite to -ous
naming acids that don’t contain oxygen
name the element/ion, add hydro, add ic, and add acid
acids have
H in the front
NH4+1
ammonium
NO3-1
nitrate
SO4-2
sulfate
PO4-3
phosphate
CO3-2
carbonate
Bond polarity
0-.5=nonpolar covalent
about .5-1.9=polar covalent
about 1.9=ionic

Octahedral 90
5,1
Square Pyramidal 90 ideal
4,2
Square Planar 90 ideal
Molecular polarity
If dipoles cancel out
- Nonpolar if all bonds are nonpolar without a lone pair
- linear always nonpolar
- usually lone pairs mean polar
Hybridization
Count clouds and subtract one
VSEPR theory
Valence Shell Electron Repulsion Theory
- Charge clouds repel each other due to Coulombic repulsion
- Terminal atoms move as far away as possible from one another as possible
- Results in distinctive geometric shapes
