How can I remember functional groups in organic chemistry?

I created a table and categorized the functional groups in organic chemistry after I committed them to memory.

The ones I included in the table were as follows: Alkene: These substances have two carbon atoms that are double-bonded and four R side chains that branch off of them.

Alkanes are hydrocarbons made up only of carbon and hydrogen, with single bonds making up every molecule.

Alkyne: Unsaturated hydrocarbon molecules with at least one triple bond between carbon atoms are known as alkynes.

Alcohols are molecules with three R group side chains branching off of an OH group and a carbon bonded to it.

Alkyl Halides: These are molecules that resemble alcohols but have a halogen bonded to the carbon instead of an OH group. Halogens are found in group seven of the periodic table and can be any element, including fluorine, chlorine, bromine, iodine, astatine, or any combination of these elements.

Amine: Amines are made up of two R group side chains, a hydrogen atom, and a nitrogen atom with a single pair of electrons.

Nitrile: Inorganic compounds containing this group are not referred to as nitriles; rather, they are called cyanides, though nitrile compounds are not nearly as toxic as cyanides. Nitriles are made up of a carbon atom triple bonded to a nitrogen atom with a lone pair of electrons.

The group that is bonded onto the carbon atom is what distinguishes each compound, even though aldehydes, carboxylic acid, amides, ketones, and esters all contain the same base—a side chain of the R group double bonded to an oxygen atom.

This is an oxygen bonded to two R group side chains in ethers, an oxygen bonded to two R group side chains in esters, an OH group in carboxylic acids, a nitrogen with two more groups bonded onto it in amides, and a carbon in aldehydes, ethers, and esters.

Use mnemonic devices, flashcards, and consistent practice to memorize and reinforce the identification of functional groups in organic chemistry.
