Polarity Flashcards
Bond Polarity
Dependent on difference in electronegativity between the two atoms
Polarity of molecule
Dependent on overall distribution of bond dipoles around the central atom
If it is a compound (ionic or metallic) instead of a molecule…
No intermolecular bonding present
If the molecule is non-polar…
Only temporary dipole-dipole attractions
If the molecule is polar and doesn’t contain H-F, H-N, and H-O bonds…
Temporary and permanent dipole-dipole attractions
If the molecule is polar and contains H-F, H-N, and H-O bonds…
Temporary, permanent dipole-dipole attractions AND hydrogen bonds.
Molecules with strongest intermolecular bonding will have the….
Highest melting/boiling points which is because they take the most energy to break
Strength of bonds:
H bonds>permanent>temporary
Larger molecules will have stronger temporary dipole-dipole forced than smaller molecules. True or false?
True
