- From R group moving around the ring:
- R group
- Ortho
- Meta
- Para

C
Cation vs. anion: positive vs. negative
- The t in cation looks like a plus sign: “ca+ion”.
- Cation is positive, anion is negative.

Cis/trans (geometric) isomer nomenclature: “Zame Zide. Epposite.”
- Z is the 2 functional groups on the same side of double bond.
- E is for opposite sides.

Cis/trans (geometric) isomers: arrangement of functional groups
- Cis starts with a C and the functional groups form a C.
- Trans, therefore is the other one by default.

G
Gibb’s free energy formula: “Zame Zide. Epposite.”
- Z is the 2 functional groups on the same side of double bond.
- E is for opposite sides.

O
Oxidation vs. reduction: electrochemical cell and electron gain/loss: AN OIL RIG CAT
- At the ANode, Oxidation Involves Loss of electrons.
- Reduction Involves Gaining electrons at the CAThode
