Saturated
Single bonds
Unsaturated
double bonds
Constitutional (structural) isomers
Have the same molecular formula but the atom has diffrent connectivity.
Stereoisomers
Any two molecules that have the same connectivity between the atoms but atoms are arranged diffrently in space
conformatinal Isomers
diffrent only by a rotation of a single bond
Cis
atoms on same side of molecule
trans
atoms on diffrent sides of the molecule
If there is an ionic bond
Show the ion as separate and charged
Aromatic Ring
Acids
Proton (H) donator
Base
Proton (H) acceptor
What happens to H₂CO₃
It is not stable so it decomposes into water and carbon dioxide
Solubility Rule of Thumb
Need <4 carbons per H binding functional group to be solule in water
Hybrid Atomic Orbital: SP
- Linear VSEPR
- 2 unused p-orbial
- Double or triple bond
Hybrid Atomic Orbital: SP2
- Trigonal Planar VSEPR
- 1 unused p-orbial
- Double bond
Hybrid Atomic Orbital: SP3
- Tetrahedral VSEPR
- 0 unused p-orbial
- single bonds
Delocalization of electrons (conjugation and resonance) is stablilizing
LUMO
lowest unoccipied molecular orbial
HOMO
Highest occupied molecular orbital
the smaller the HOMO, LUMO gap
the longer the wavelenght
Congucation leads to
a smaller HOMO-LUMO gap
Calculating Formal Charge
valence shell electrons(free atom)-#lone pair electrons - 1/2 # bonding electrons
Coordinate covalent bond
where electrons are coming from one atom/molecule and are going to the metal
Ligands
Atoms/molecules that are binding to the metal
Chelating Ligands
can bond more than once (multiple doantion sites)
Cordination number
number of groups bonded to the metal
Stability Rules
- octet rule-All atoms have there octet unless ir is 3rd period or lower then it can have an expanded octet
- Minimize formal charges
- Have negative charge on the more electronegative atoms
Boiling Point
- the stronger the IMFs the higher the boiling point (and melting point)
- IMFs= the bonds molecules can make with other molecules
- Hydrogen bonds - strong happen between N,O,F and hydrogen
- Dipole-Dipole
- Dispersion forces - weak
