molecular covalent structures Flashcards
1
Q
molecular covalent structures have low melting and boiling points why?
A
The van der Waals’ forces between the
molecules are weak and require little energy
to break
2
Q
are the diatomic elements molecular covalent structures
A
yes
3
Q
why cant molecular covalent structures conduct energy
A
They do not contain charged particle
4
Q
why are molecular covalent structures insoluble in water
A
dont have to explain
5
Q
what are the properities in molecular covalent structures
A
insoluble
low conductor
low melting point and boiling point
6
