Document Summary
Most living org contain about 70% of water. Density of liquid water > density of ice. In ice, the thermal energy is taken out slower movement as it becomes more dense, its bonds form with other h 2 o molecules. As the temperature increases (gets colder), the density increases as well. Methyl, non-polar, van der waals and hydrophobic. Hydroxyl, polar, hydrogen bond, no permanent dipole, can participate in reactions. Carboxylic acid, polar, hydrogen bond, lower ph. In order from least to greatest interaction: ch 3 , oh, cooh. Would ch 3 ch 2 ch 2 ch 2 ch 3 non-polar and hydrophobic can pass through membrane. If it enters the cell, to prevent it from going outside change the functional groups. Easily changed more dynamic than covalent bonds. A hydrogen bond is weak if the bond where the h meets with fon is bent. These forces occur due to permanent, transient, or induced dipoles that occur in all molecules.
