[[Organic Chemistry]]
Simplest organic compounds are hydrocarbons, composed solely of carbon and hydrogen.
Non-polar, as they contain only hydrogen and carbon.
They are classified as aromatic or aliphatic. Aliphatic hydrocarbons have carbon atoms bonded in chains or rings, including straight chains and cyclic alkenes, alkanes and alkynes. Aromatic hydrocarbons are hydrocarbons based on aromatic benzene group.
Alkanes are hydrocarbons that only contain single bonds, alkenes contain double bonds and alkynes contain triple bonds.
Alkanes in the shape of a ring are called cycloalkanes. Alkanes not in the shape of rings have formula $C_nH_{2n+2}$. Cycloalkanes are in the shape of rings and have the formula $C_nH_{2n}$. Straight chain alkenes with one double bond have the same formula as cycloalkanes. Straight chain alkynes with one triple bond have the formula $C_nH_{2n-2}$.
Functional groups are groups of reactive bonded atoms that appear in all members of a family. Reactive double bonds are the functional group of alkenes.
# Naming Organic Compounds
Naming organic compounds usually follows the pattern of prefix + root + suffix.
Root names:
| Number of Carbon atoms | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| ---------------------- | ---- | --- | ---- | --- | ---- | --- | ---- | --- | --- | --- |

Species is a group in organism that interbreed in nature and produce fertile offspring. Gaps though, bacteria don't sexually reproduce, and there are separate species that are able to mate and create fertile children.
Three types of species.
* Morphological Species:
* Studies shape, size, physics, structural features.
* Simple, quick.
* Most populations have variation.
* Biological Species:
* Ability to reproduce in nature and produce fertile offspring.
* Most commonly accepted definition, objective.
* Can't test on asexually reproducing, extinct, and/or physically separated organisms.
* Phylogenetic:
* Studies evolutionary history and relationships among organisms.

Organic compounds are compounds that contain carbon. It was originally classified as compounds originating from living beings, but a scientist made an organic compound inorganically using ammonium cyanate.
Carbon usually forms 4 covalent bonds. If a compound contains only single bonds, then it's saturated, unsaturated otherwise.
Carbons unique bonding allows it to form many shapes, including rings and chains.

fallacy fallacy - calling out fallacies without actually providing a counterargument | Ad Hominem | Insulting opposition without argument. |
appeal to hypocrisy/tu quoque - calling out another persons hypocrisy like eg you hate this game but you dont make any | Ad Lapidem (Appeal to the stone) | Saying no without an argument. |
possibiliter ergo probabiliter/appeal to probability - this is likely so it must be true | Fallacy Fallacy | Calling out fallacies without argument. |
false dilemma- presenting something as either this or that when there could be more options | Tu Quoque (Appeal to Hypocrisy) | Calling out hypocrisy, example being "You say this game is bad, but you don't make any." Such an argument makes no sense. |
straw man - misrepresents opponents argument to make it easier to attack, eg "gmos are bad? so youre saying you like farmers losing money because of bugs?" | Possibiliter Ergo Probabiliter | Claiming that something is likely so it must be true. |
cherry picking - picks specific parts that support their claim and ignore the countless other things that go against | False Dilemma | Claiming something is either this or that, despite it being a gradient or there being more possiblilities. |
| Straw man | Misrepresenting argument to make it easier to counter, example being "You dislike pedophiles? Are you saying disciplining children is bad?" |
| Cherry Picking | Picks out specific parts of evidence that supports their claim despite there being tons of other evidence that go against it. |
| Proof by Assertion | Reiterating argument without new evidence. |
| Non Sequitur | A statement that does not follow the logical flow of the previous. |
| Bandwagon | Belief that claim is right because tons of people do it. |
| Slippery Slope | Claiming one minor step will lead to major consequences. |

# Summary
* Atoms have a small positive nucleus made of protons and neutrons and are usually surrounded by electrons.
* Nuclear notation: $^A_ZX$, Z protons A mass X atomic symbol
* Ion is atom with net charge.
* In Bohr model, Coulomb force between nucleus and electrons provides centripetal force for circular orbit: $F_e=k\frac{q_1q_2}{r^2}$ supplies $F_{net}=m\frac{v^2}{r}$
* Circumference must equal a whole number of de Broglies wavelength: $n\lambda=2\pi r$
* Atomic structure here is only defined as energy levels, no probability functions yet.

# Summary
* Quantum theory developed because classical physics can't explain atomic spectra, blackbody radiation or photoelectric effect.
* Photons are electrically neutral massless particles.
* $E=hf$, with $h$ being Planck's constant.
* Photons travel at $c=$ 299792458 m/s (or $c=3*10^8$ for simplification) in a free space, and are slowed by a factor of the medium's index of refraction.
* Particles like electrons show wave behavior, quantified by de Broglie wavelength $\lambda=h/p$. Wavelength increases as momentum decreases.
* Quantum effects matter when a particles de Broglie wavelength is comparable to the system.
* In bound systems, energy and momentum are discrete.
