VSEPR Flashcards
Ionic crystals
Are lattice structures
Strong since cattions and anions interact and solid
What state are ionic crystals in
Solid
Formula unit
Indicates smallest ratio of each unit in crystal form
Molecular structures
Solid, liquid, gas at room temp
What is another word for molecular structures
Covalent bonds
Stereochemistry
Study of how structure effects physical and chemical properties
VSEPR stands for
Valence shell electron pair repulsion
What is VSEPR
Prediction of 3D shape of molecule
What do electron pairs do to eachother
Repell
What does A stand for
Central atom
What does X stand for
Bonding pair
What does E stand for
Lone pair
What does Linear show
All bonding pairs and flat
What is Trigonal Planar
All bonding pairs and flat with three
Tetrahedral
All bonding pairs with four and not flat
Trigonal Pyramidal
Three bonding pairs with one lone pair and bent
Bent
Has two bonding and two lone pairs and bent
How many VSEPR diagrams are there
Linear

Trigonal Pyramidal
Bent
What are dipole arrows
Show which side has more EN
What is the fancy looking S
Shows which side is negative and positive
