4.1.2 - simple molecular substances Flashcards
1
Q
why do simple molecular substances have very low boiling points
A
there are weak intermolecular forces between the molecules that don’t require a lot of energy to break
2
Q
in simple molecular substance, as the molecular mass increase ….
A
so does the strength of the weak intermolecular forces -> this results in a higher boiling point
3
Q
what does electrical conductivity require?
A
charged particles that can move freely
4
Q
why can’t simple molecular substances conduct electricity?
A
the molecules are neutral
5
Q
why is the boiling point of C60 fullerene not as low as other molecules?
A
it has a high molecular mass
6
Q
why is C60 a soft and slippery solid?
A
the molecules can roll over each other easily
7
Q
why is C60 an electrical insulator?
A
the molecules are neutral
