Molecular interactions

Question 1

What are stereoisomers?

Answer 1

same molecular formula but different arrangements of atoms in 3D space

Question 2

What are the 2 types of isomers?

Answer 2

• Geometric: cis/trans

- CHIRAL: enantiomer (4 diff. groups bound to C = non-superimposible mirror image)

Question 3

Hydrogen bond

Answer 3

Hydrostatic attraction of H to a highly electronegative atom (O, N, F)

Question 4

Induced dipoles

Answer 4

nearby molecules form temporary dipoles (polar) with other molecules = weak electrostatic attraction from partial + and partial -

Question 5

Dispersion force

Answer 5

random movement of atoms forms temporary dipoles

Question 6

Hydrophobic effect

Answer 6

water optimises H bond w/ itself & exclude interactions w/ non-polar molaecules
