Use VSEPR to predict bond angles about each atom of carbon, nitrogen, and oxygen inthese molecules.
Bio-organic Chemistry Organic=CARBON o 4 bonds in carbonate because 4 bonds forms lowest energy state o long chains- hexane o stable C-C bond and Si-Si bond. C-C bond is stronger because have to share valence electrons, Si electrons are way further away from nucleus. Bonds break with activation energy. To increase activation energy: heat; the sun. Carbon- 346 kJ/mol to break bond Si- 233 kL/mol to break bond o reactions can be controlled When you eat and take things apart, we take them apart step by step Sugar becomes carbon dioxide (lowest form of carbon) and breath it out Coulumb’s Law o The force of attraction (or repulsion) between two charges is determined by: Magnitude of charge and distance between charges Bond gets stronger as charge increases and as distance decreases Ex: Mg2+ with O2+ would be stronger than Na+ with Cl- because 2 is bigger charge than 1 Overlap and bonding o Sigma bonds Head to head overlap, direct interactions, strongest type of bonds If e-s are RIGHT between nuclei, that’s a really strong bond o Pi bonds Side to side overlap E- density above and below the internuclear axis
