(a)
Interpretation:
The characteristic a compound should have to experience a London dispersion force should be given.
Concept Introduction:
Intermolecular forces in a molecule are the important factor which is responsible for the physical changes of the molecule.
The intermolecular forces in gases are negligibly small and the forces are comparatively stronger in liquids and the intermolecular forces are highest in solids.
The stronger the intermolecular forces, closer will be the molecules in contact and thus higher will be the boiling point and melting point of the substance.
Three types of intermolecular forces:
- London dispersion
- Dipole-dipole
- Hydrogen bonding
(b)
Interpretation:
The characteristic a compound should have to experience a Dipole-dipole force should be given.

For example, 1M = 1 mole/L. To determine how many grams of a substance is equal to one mole the molecular mass is needed (we will not explore this in this lab rather this is taught in your Chemistry subjects). The general formula for making a dilution solution is the following: CıV1 = C2V2 where C: = the original concentration of stock solution Vi = the volume of stock solution needed to make working solution C2 = the desired concentration of working solution V: = the desired final volume of working solution For Educational Purposes Only SLSU-TO/NCMatondo 18 What would be the working stock concentration (in molarity) if you diluted 250 ul of a stock concentration of 10 µM in a total volume of 1 mL?
