Document Summary
3)most polar bond--> o-h because on opposite ends of the electronegativity scale. 4)if you want a molecule that is highly polar, look for one that contains--> h-n: look for more electronegative, it is the most polar. 5)each water molecule is joined to four other water molecules by hydrogen bonds. 6)unequal sharing of electrons is polar: the electrons spend more time with the oxygen of the water molecule than with the hydrogens of water. A: amino group (nh2) (also behaves like a base) B: phosphate group (p) (major role in energy transfer because phosphate groups are components of atp. C: carbonyl group (also a characteristic of a ketone because a carbonyl group in the middle of a carbon skeleton characterizes ketones. D: hydroxyl group (also is a functional group characteristic of alcohol) C and h have approximately equal electronegativities, so electrons are shared equally in ch4.
