2.6 Shapes of Molecules and Intermolecular Forces Flashcards
1
Q
V.S.E.P.R Theory
A
Electron pairs have like charges so they repel each other that produces the shapes of molecules.
2
Q
Electronegativity
A
The ability to attract electrons in a covalent bond
3
Q
Permanent dipole
A
a molecule with a partial charge.
4
Q
London forces
A
Induced dipoles creating intermolecular forces
5
Q
Non-polar bonds
A
the bonded electrons are shared equally
6
Q
Polar bonds
A
The bonded electron pairs are shared unequally.
7
Q
Hydrogen bonding
A
the bonding that occurs between a FONCl and Hydrogen
8
Q
Why is ice less dense than water?
A
Hydrogen bonds hold the water molecules in an open lattice structure. Therefore the water molecules in ice are further apart.
9
Q
Why does water have a high melting/boiling point?
A
H bonds stronger than London Forces that take more energy to break.
