Molecular Solids Flashcards
1
Q
Types of particle
A
Molecules
Held in a 3D lattice structure.
2
Q
Attractive fores
A
Weak intermolecular forces
3
Q
Melting point
A
Low, only a small amount of energy need to overcome weak intermolecular forces.
4
Q
Are molecular solids soft and brittle when deformed?
A
Yes, weak intermolecular forces are easy to separate.
5
Q
Are polar molecular substances soluble in polar solvents?
A
Yes
6
Q
Are non-polar molecular substances soluble in non-polar solvents?
A
Yes
7
Q
Do molecular solids conduct electricity?
A
No, there are no charged particles (electrons or ions) that are free to move within the structure.
When melted it will still not conduct electricity.
