Chemical Bonding, Properties and Structure - Properties of Small Molecules Flashcards
(4 cards)
1
Q
what is usually the relative melting + boiling points of substances that consist of small molecules
A
low
and they are usually gases or liquids
2
Q
what is the strength of the forces between the molecules in small molecules
A
weak
it is these intermolecular forces that are overcome, not the covalent bonds when the substance melts or boils
3
Q
the larger the size of the molecules the larger the size of the _____________
A
intermolecular forces, therefore larger molecules have a higher melting and boiling points
4
Q
why dont these substances conduct electricity
A
because the molecules do not have an overall electric charge
