List of chemistry mnemonics
A mnemonic is a memory aid used to improve long term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics. This article contains the list of certain mnemonics in chemistry.

Reactions and ions
Redox reactions
A redox reaction is a chemical reaction in which there is a change in oxidation state of atoms participating in the reaction.
Ions
An atom (or ion) whose oxidation number increases in a redox reaction is said to be oxidized (and is called a reducing agent). It is accomplished by loss of one or more electrons. The atom whose oxidation number decreases gains (receives) one or more electrons and is said to be reduced. This relation can be remembered by the following mnemonics.
- Leo says Ger! or Leo the lion, Ger! can be used to represent Loss of electron is oxidation; Gain of electron is reduction.[19][20]
- Oil Rig: Oxidation is loss; Reduction is gain (of electrons).[21]
Cations and anions
Cations are positively (+) charged ions while anions are negatively (−) charged. This can be remembered with the help of the following mnemonics.
- Cats have paws ⇔ Cations are pawsitive.[22]
- Ca+ion: The letter t in cation looks like a + (plus) sign.[23]
- An anion is a negative ion. (An
egativeion ⇒ Anion).[24]
Cation vs. anion: positive vs. negative
The t in cation looks like a plus sign: "ca+ion".
Cation is positive, anion is negative.[25]
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.[25]
'LOAN'- Left Anode Oxidation Negative [ on the left on side of the cell reaction (in written form), Oxidation takes place ]
Electrodes
An electrode in which oxidation takes place is called an anode while in that which reduction takes place is called cathode. This applies for both electrolytic and electrochemical cells, though the charge on them reverses. The red cat and an ox mnemonics are useful to remember the same.
- Red cat: Reduction at cathode
- An ox: Anode for oxidation.[26]
- The words oxidation and anode, both begin with vowels.
- Also, both reduction and cathode begin with consonants.[24]
- Fat Cat: electrons flow From Anode To Cathode
Compounds
Diatomic molecules
Molecules exhibiting diatomic structures can be remembered through the following mnemonics.
Hydrogen, Oxygen, Nitrogen, Fluorine, Chlorine, Bromine, Iodine |
- I Have No Bright Or Clever Friends.
- I Bring Clover For Our New Horse.
- Have No Fear Of Ice Cold Beer. [27]
- Help Our Needy Class Find Brains Immediately.
- Horses Need Oats For Clear Brown Eyes (I's).
- Her Nana's Only Functioning Clicker Broke Instantly.[28]
- BrINClHOF: say Brinkelhof.[29]
- HONClBrIF The name of the imaginary chemistry goose. Say "Honk-Cool-Brief."
- I Bring Clay For Our New House.[9]
- Have No Fear Of Cute, Innocent Baby twins.
Hydrogen bonds
Hydrogen forms hydrogen bonds with three elements which are nitrogen (N), oxygen (O) and fluorine (F). The names of these elements can be remembered by the following mnemonic.
- Hydrogen is FON! (fun).[24]
Polyatomic ions: −ate and -ite ions
Sulfate, Phosphate, Carbonate, Chlorate, Bromate, Iodate, Nitrate |
- Super Popeye Constantly Clubbed Brutus In Nevada.
Nitrate, Bromate, Carbonate, Iodate, Chlorate, Chromate, Sulfate, Phosphate |
- Nick Brit the Camel ate an Inky Clam with Crêpes for Supper in Phoenix.
Number of consonants denotes number of oxygen atoms. Number of vowels denotes negative charge quantity. Inclusion of the word "ate" signifies that each ends with the letters a-t-e. To use this for the -ite ions, simply subtract one oxygen but keep the charge the same.
Organic chemistry
Carboxylic acids
Common names of homogeneous aliphatic carboxylic acids,
Formic, Acetic, Propionic, Butyric, Valeric, Caproic |
- Frogs Are Polite, Being Very Courteous.[30]
Dicarboxylic acids
The sequence of dicarboxylic acids can be remembered with following mnemonics.
Oxalic, Malonic, Succinic, Glutaric, Adipic, Pimelic, Suberic, Azelaic, Sebacic |
- Oh My Such, Good Apples.[31]
- Oh My Stars, Green Apples.
- Oh My, Such Good Apple Pi.e., Sweet As Sugar.[32][33]
- Oh My Stars, Go Ahead Please[24]
Aromatic compounds
m-directing groups
Quaternary amino | Ester | Sulfonic acid | Nitro | Carbonyl | Carboxyl | Cyano |
(-NR3+) | (-COOR) | (-SO3H) | (-NO2) | (-CHO) | (-COOH) | (-CN) |
- Queen Elizabeth Second's Navy Commands, Controls, Communicates.[34]
o,p-directing groups
Alkyl | Halogen | Alkoxyl | Amino | Hydroxyl | Amide | Phenyl | ||
(R) | (X) | (OR) | (-NH2 | -NHR | -NR2) | (OH) | (NHCOR | (C6H5) |
- AHA AHA P.[34]
Note: -NH2,-NHR and NR2 are para directing groups but not -NR3+
E-Z notation for isomers
"Zame Zide. Epposite.":
Z is the 2 functional groups on the same side of double bond.
E is for opposite sides.[25]
Cis–trans isomerism
Cis starts with a C and the functional groups form a C.
Trans, therefore is the other one by default.[25]
Benzene ring: order of substitutes
"Benzene likes to ROMP":
- From R group moving around the ring:
R group
Ortho
Meta
Para.[25]
Biochemistry
Essential amino acids
Isoleucine, Leucine, Lysine, Serine, Tyrosine, Glycine, Alanine, Cysteine, Glutamate, Asparate, Arginine, Glutamine, Histadine, Methionine, Phenylalanine, Threonine, Tryptophan, Valine, Histidine, Asparagine, (Selenocysteine - usually omitted) |
- PVT TIM HaLL[35] and TT HALL Very IMPortant.[36]
- MATT HILL, VP Matt Hill is the Vice President
- LIFT HIM KIW(V)I
- TV FILM HW(R)K.
- Any Help In Learning These Little Molecules Proves Truly Valuable.[37] This method begins with the two amino acids that need some qualifications as to their requirements.
- There as [a] fat man [that] hated vanilla icing, [but] loved Kit-Kats.
Krebs cycle
To remember Krebs cycle (citric acid cycle, tricarboxylic acid cycle);
Citrate → Aconitate → Isocitrate → Oxalosuccinate → α-Ketoglutarate → Succinate → Fumarate → Malate → Oxaloacetate |
- Caesar’s Armies Invaded Other Kingdoms Searching For Many Oranges.[14]
Citric Acid Is One Key Substrate For Mitochondrial Oxidation
Plant nutrients
To remember the elements necessary for agriculture;
Carbon, Hydrogen, Calcium, Iron (Fe), Magnesium (Mg), Manganese (Mn), Copper (Cu), Molybdenum, Chlorine (Cl), Boron |
- C (see) Hopkins CaFe, Mighty-good Man, Cu (see your) Money, hope they are Closed or out of Business.[38]
For remembering macronutrients;
Carbon, Hydrogen, Oxygen, Phosphorus, Potassium, Nitrogen, Sulfur, Calcium, and Magnesium |
- C. HOPKiN'S Ca Mg (C. Hopkins coffee mug).
C H O N P K Ca Mg S {CHO "N"ever "P"unch "K"ittens they'll "Ca"ll aunt "Mag" and then you are "S"crewed.
