Anion vs. cation charge

ANion is A Negative ion.

 

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 orWEDD’M?”:

ROMP: Substituents in order: R-group, Ortho, Meta, Para.

HOPEDHalogens are Ortho, Para, Electron withdrawing, Deactivating.

ADOPt: Addititive substituents Direct Ortho & Para.

WEDD’MWithdrawing Electrons Deactivates, Directs Meta.

 

Benzene ring: order of substituents

Meta: the two sticks representing functional groups make a capital letter with the ring.

Otho: can close the top of the functional groups and make a boxy capital letter O.

Remaining one must therefore be para.

 

Benzene ring: order of substituents

“Benzene likes to ROMP“:

From R group moving around the ring:

  • group
  • Ortho
  • Meta
  • Para

 

Benzene ring: order of substituents

OMPenis!”:

Putting R at top and moving around the ring:

  • Ortho
  • Meta
  • Para
  • Penis is the one pointing down, like the penis of a man pointing downwards.

 

Cathode: what happens during electrolysis

Current Carries Cations to the Cathode for reduCtion.

 

Cation vs. anion: positive vs. negative

The 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) 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 and the functional groups form a C.

Trans, therefore is the other one by default.

 

Gibb’s free energy formula

Good Honey Tastes Sweet”:

(delta)– T(delta)S

 

Orbital names before alphabetical order begins

Sober People Don’t Find Good IKilling”:

Orbital names for electrons are S,P,D,F,G,I,K. After that, alphabetical order begins.

 

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.

 

Oxidation vs. reduction: electron gain/loss

LEO the lion says GER“:

Lose Electrons = Oxidation.

Gain Electrons = Reduction.

 

Oxidation vs. reduction: electron gain/loss

OIL RIG:

Oxidation ILoss (of electrons).

Reduction IGain (of electrons).
