van der waals bonds
formed by the complementray partial charges or dipoles that are induced in the electron densities of adjacent atoms when the electronic orbitals of the two atoms approach to a close distance
formed when 2 hydrophobic side chind approach each other in such a way as to exlude water between them. The strength of hydrophobic bonds are not due to some intrinsic attraction of the nonpolar groups to each other

true because of steric hinderence
