Benzene ring: effects of substituents on further additions
"Benzene likes to ROMP. We HOPED she's be safe, but now she's knocked up. ADOPt or WEDD'M?":
ROMP: Substituents in order: R-group, Ortho, Meta, Para.
HOPED: Halogens are Ortho, Para, Electron withdrawing, Deactivating.
ADOPt: Addititive substituents Direct Ortho & Para.
WEDD'M: Withdrawing Electrons Deactivates, Directs Meta.

Benzene ring: order of substituents
Meta: the two sticks representing functional groups make a capital letter M with the ring.
Otho: can close the top of the functional groups and make a boxy capital letter O.
 See diagram.
Remaining one must therefore be para.

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
The letter "Z" is written in a zigzag way. If you draw a vertical line splitting it down the middle then its
the same halves (same sides of double bond). The letter "E" is written differently so a vertical line splits it
into different halves (different sides of double bond).

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.
