CH 10 Structure and Bonding Theories

Whats the main idea of VSPER theory

electron domains/groups will repel eachother in structures causing molecules to have different shapes

in VSPER structures the shape is assigned around _____________________

a central atom

What properties does molecular geometry affect

physical and chemical

which physical/chem properties does molecular geo affect (according to textbook)

boiling pt, freezing pt, density, and reaction type

What do you need to know to determine a molecules geometry

the number of electron domains surrounding a central atom in its structure

the term “electron domain” refers to:

the surrounding lone pairs or bonds around a central atom

electron domain vs group

theyre the same

T/F when counting electron domains we count the individual lone pairs and bonds

F

How to count electron domains

count the atoms bonded to a central atom and the central atoms lone pairs if it has any

Electron pair geometry VS Molecular geometry

electron pair geometry describes the shape of a molecule including its bonds and lone pairs, molecular geometry excludes lone pairs,focusing on the shape taken by the other electron domains in response to the lone pairs

define diaople moment

a quantitative measure of an atoms polarity
