What type of molecular bond is the weakest
London dispersion
what type of elements form hydrogen bonds
OH, NH, FH
How do polar bonds form molecularly
between opposing charges on the molecule
what is a net dipole
the direction the EN is going through the molecule
what element has the negative charge in a polar molecule
the element that the electron is transfering too (stronger pull)
can polar bonds form with non polar molecules
no
If a nonpolar substance is placed in a polar substance what will happpen
the non-polar substance will try to limit the amount of surface that is touching the polar substance
what causes london dispersion forces
electron movement, this is why they are present in every bond.
Solubility rules
non polar substances are only soluble in other non polar substances. Polar substances are only soluble in other polar substances.
