Polar hydrophilic - Study guides, Class notes & Summaries

Valence Ans- number of e- in outermost shell, determines number of bonds the atom can form 4 types of bonds Ans- covalent, ionic, hydrogen, van der waals Hydrogen bonding Ans- electrostatic attraction between partially positive hydrogen atom and a partially negative, highly electronegative atom van der Waals forces Ans- weak attractive/repulsive forces resulting from the movement of electrons, creating temporary regions of partial pos. and neg. charge if difference in EN between to...

Explain the properties of water, including cohesion, adhesion, polarity, heat of vaporization and solvent properties? - Answer - water attracts to itself - water attracts to anything charged - most important - uneven sharing valence electrons, partial negative charge near oxygen atom + 2 partial positive charge near hydrogen atom - large amount of heat to change from liquid to gas, evaporating off skin to cool - polar makes good solvent for ionic and polar substances, hydrophilic attracts ...
