simple molecules Flashcards
1
Q
do small molecules have low melting and boiling points?
A
yes
2
Q
how does the size of a molecule affect the melting and boiling points?
A
the larger the molecule the more attractions so therefore more energy (and so heat) is required to break it down. (same for the smaller the molecule)
3
Q
do they conduct electricity?
A
no
4
Q
why don’t they conduct electricity?
A
they have no delocalised electrons so no electricity can flow through it.
5
Q
describe an intermolecular force
A
forces that exist between and connect molecules
