Intermolecular structure and bonding Flashcards
1
Q
what is a drug?
A
a chemical that changes biochemistry through a chemical reaction.
2
Q
Van der Waals
A
weakest, holds non polar molecules together, 2x induced dipoles
3
Q
Hydrophobic effect
A
water is re ordered into a structure around the molecule , lowered entropy, passage through cells
4
Q
ion dipole interactions
A
controls the orientation of the molecule
5
Q
covalent
A
between specific molecules/ elements, selective
6
Q
Hydrogen bond
A
between a pair of electrons and a polarised proton of a neighbouring molecule
7
Q
electrostatic interactions
A
between molecules of opposite electronic charges eg. NH3+ and CO2-. stronger in hydrophobic environment. non directional
8
Q
dipole- dipole
A
parallel = disfavoured, anti parallel = favoured
