Properties of Simple Molecular Substances: Flashcards
What is a simple molecular substance?
= atoms are covalently bonded to eachother
= small molecules with a fixed number of atoms
Why do simple molecular substances have a low melting + boiling point?
= due to intermolecular forces being low
= weak
= electrons increases the strength of vander wall forces increases
In a solid form what is it called?
= simple molecular lattice
What does solubility depend on?
= whether it is polar or non-polar
What is the solubility of non-polar substances?
= dissolve well in non-polar solvents
= the solvent molecules form vanderwall forces with the non-polar substance
= INSOLUABLE in polar solvents
What is the solubility of polar substances?
= dissolves well in polar solvents
= forms the same intermolecular bonds
= INSOLUABLE in non-polar solvents
What is the conductivity?
= do not contsined mobiel charged prticles
=c annot conuct electricity.
