Molecular interactions Flashcards
1
Q
What are stereoisomers?
A
same molecular formula but different arrangements of atoms in 3D space
2
Q
What are the 2 types of isomers?
A
- Geometric: cis/trans
- CHIRAL: enantiomer (4 diff. groups bound to C = non-superimposible mirror image)
3
Q
Hydrogen bond
A
Hydrostatic attraction of H to a highly electronegative atom (O, N, F)
4
Q
Induced dipoles
A
nearby molecules form temporary dipoles (polar) with other molecules = weak electrostatic attraction from partial + and partial -
5
Q
Dispersion force
A
random movement of atoms forms temporary dipoles
6
Q
Hydrophobic effect
A
water optimises H bond w/ itself & exclude interactions w/ non-polar molaecules
