u3: VSEPR Flashcards
1
Q
wht does molecular shape determine?
A
a molecule’s physical and chemical properties
2
Q
molecular shape depends on….
A
- nature of atoms involved in bonding
- bond angles
- bond distance
3
Q
wht does VSEPR stand for
A
Valence Shell Electron Pair Repulsion
4
Q
what is VSEPR theory
A
- predicts shape of molecules bc electrons repel each other
- uses lewis structure to examine bonding and non-bonding pairs
5
Q
bonding electrons
A
valence electrons that are shared between atoms to form covalent bonds
6
Q
non-bonding electrons/lone pairs
A
valence electrons that are not shared with other atoms
7
Q
what do electrons want?
A
- to maximize space
- this means that the molecule shape depends on number of bonding electrons/lone pairs around central atom
8
Q
A
