molecular covalent structures Flashcards
molecular covalent structures have low melting and boiling points why?
The van der Waals’ forces between the
molecules are weak and require little energy
to break
are the diatomic elements molecular covalent structures
yes
why cant molecular covalent structures conduct energy
They do not contain charged particle
why are molecular covalent structures insoluble in water
dont have to explain
what are the properities in molecular covalent structures
insoluble
low conductor
low melting point and boiling point
what are the weak force of attraction between the molecules called
van der waals forces
what are the molecular covalent structures not including diatomic elements
hcl
NH3
H20
CO2
what to diatomic elements have
molecular covalent structures
covalent bonds
van der waals forces etc
whats the test for water and whats its change
anhydrous copper sulfate
from white to blue
whats the boling point for water
100
what colour is chlorine
yellow/green
