Chapter 1
organic vs inorganic
- oranic molecules Contain carbon, essential to life
- It is possible to convert some inorganic molecules to organic molecules
- Ammonium cyanate -> urea
- not all inorganic molecules contain carbon, but all organic molecules contain carbon
Structure of an atom (carbon)
- protons and neutrons are surrounded by electron field
- "orbitals" is a simple way of defining energy levels of groups of electrons
- P orbital has higher energy compared to S orbital
- \(1s^22s^22p^2\)
- carbon has 4 valence electrons with a maximum of 8
- \(1s^22s^22p^2_x2p^2_y2p^2_z\) is the maximum configuration
- Aufbau principle: an electron goes into the lowest energy orbital
- pauli exclusion principle: 2 electrons per orbital maximum (spin up, spin down)
- Hund's rule: 2 or more orbitals of the same energy(degenerate), electrons will go into different orbitals
