INORGANIC COMPOUNDS
ORGANIC COMPOUNDS
Small in size No carbon (some exceptions) Not a good source of energy Found on earth and in living
things Ex: water, acids, bases, salts
Large in size All contain carbon, and usually
hydrogen >CO2 is inorganic Good source of energy
Ex: carbs and lipids Only in living things Other examples: Proteins,
DNA, and RNA Also known as macromolecules
CHEMISTRY OF WATER
POLARITY• Oxygen – electronegative & selfish and
hogs the electrons• Electronegative refers to its ability to attract
electrons
• Polar covalent bond created between H & O• Polarity- unequal sharing of electrons• Results in a positive (H) and a negative (O)
dipole
HYDROGEN BONDING
•Hydrogen bond- when H is weakly bonded to a more electronegative atom•Caused by the polarity of
• A liter of ice weighs less than a liter of water• Caused by the hydrogen bonds- spread molecules out• What would happen if ice was more dense than water? What
effect do you think that would have on life?
