Simple molecular structures Flashcards
(5 cards)
1
Q
What states of matter do small molecules usually form?
A
Gases or liquids
Small molecules typically have low melting and boiling points.
2
Q
What type of forces exist between small molecules?
A
Weak intermolecular forces
These forces are responsible for the physical properties of small molecules.
3
Q
What is overcome when a substance melts or boils?
A
Intermolecular forces
This is different from breaking covalent bonds.
4
Q
How do intermolecular forces change with the size of molecules?
A
They increase with size
Larger molecules have higher melting and boiling points.
5
Q
Do substances with small molecules conduct electricity?
A
No
Molecules do not have an overall electric charge.
