Types of Bonds Covalent Bonds Sharing of electrons Strong ~11o kcal to break Close ~.1nm apart # bonds: O 2 bonds H 1 Bond C 4 bonds N 3 bonds S 2 bonds P 5 bonds (doesn’t follow rule) Non-polar Covalent Bonds Share electrons 2 of te same atom Exs: H 2 O 2 or CH 4 Can pull equally on atoms they share Polar Covalent Bonds One atom pulls on shared electrons more than anther (ex: H2O) Electronegative atoms don’t share electrons equally *C is not electronegative Electronegativity increases going up the PT and to the right of the PT

Unformatted text preview: Non-Covalent Bonds • No shared electrons • Weak ~1-7 kcal to break • Length ~ 0.3 nm (3X as far) • Reversible Hydrogen Bonds (polar) Ionic Bonds (polar) Van der Waals Attractions (non-poar) • H-donor-donates a H + • H-acceptor-accepts a H +-has a partial (-) charge-usually N or O • Strongest of non-covalent bonds • Involves complete transfer of electrons • Hydrophobic interactions...
