Type Of Solid - Molecular

Question 1

Non-metal and Non-metal form?

Answer 1

Molecular solid

Question 2

What particles are molecular solids?

Answer 2

Molecules

Question 3

Forces of molecular solids

Answer 3

Weak intermolecular forces

Question 4

Why do molecular solids have a LOW melting point?

Answer 4

Weak intermolecular forces = do not require much energy to overcome thus giving it a lower temperature melting point

Question 5

Relate the weak intermolecular forces to brittleness of molecular solids

Answer 5

Weak intermolecular forces allow molecules to be easily separated so this makes them easy to break thus making it brittle&soft

Question 6

Why can’t liquid and solid state of molecules not conduct?

Answer 6

The don’t contain mobile/ moving charged particles thus cannot conduct in liquid or solid state

Question 7

Non-polar molecules solubility in non-polar solvents(ie. cyclohexane)

Answer 7

Both molecules have similar intermolecular forces between them so weak forces also exist between the 2 molecules

Question 8

Polar molecules solubility in water

Answer 8

Soluable in polar solvents because of similar weak intermolecular forces so can also exist between the 2 different molecules
