Simple Molecular Substances Flashcards
do simple molecules contain strong or weak covalent bonds?
strong
what happens to the weak intermolecular forces between the molecules when simple molecule substances boil?
the weak intermolecular forces break
what happens as molecular mass increases?
the strength of the weak intermolecular forces increase - this results in the boiling point increasing
what does electrical conductivity require?
charged particles that can move freely
are there charged particles in a simple molecular substance?
no
why can simple molecular substances never conduct electricity?
the molecules are neutral
what is C60 fullerene made up of?
its a unique simple molecule composed of sixty carbon atoms in a ball
does C60 fullerene have a high or low boiling point?
low - but not as low as other molecules because of its high molecular mass
why is C60 fullerene soft and slippery?
the molecules can roll over each other easily
why is C60 fullerene an electrical insulator?
the molecules are neutral
