When all the atoms present in the monomers are retained in the polymer product
Addition polymerization
When all the atoms present in the monomers are retained in the polymer product. Addition polymerization. Addition polymerization is a process where small molecules, called monomers, join together to form a large chain without losing any atoms.

A reaction in which an atom or molecule is added to an unsaturated molecule
Addition reaction
A reaction in which an atom or molecule is added to an unsaturated molecule. Addition reaction. An addition reaction happens when new atoms attach to a molecule that has double or triple bonds, making it more saturated.

An organic compound derived from ammonia by replacement of one or more hydrogen atoms by organic groups
Amine
An organic compound derived from ammonia by replacement of one or more hydrogen atoms by organic groups. Amine. In simple terms, an amine is a molecule that is like ammonia but has one or more hydrogen atoms replaced by carbon-containing groups.

Polymers formed through a condensation reaction
Condensation polymerization
Polymers formed through a condensation reaction. Condensation polymerization. Condensation polymerization is a chemical process where small molecules join together to form a large polymer, releasing a small molecule like water as a byproduct.

Ethanol that has additives to make it bad-tasting and poisonous to discourage recreational consumption
Denatured alcohol
Ethanol that has additives to make it bad-tasting and poisonous to discourage recreational consumption. Denatured alcohol. It is ethanol that has been chemically altered to prevent people from drinking it.

A organic chemical reaction in which a pair of atoms are removed from a molecule
Elimination reaction
A organic chemical reaction in which a pair of atoms are removed from a molecule. Elimination reaction. In an elimination reaction, parts of a molecule are removed to form a simpler molecule, often creating a double bond.

A group of atoms responsible for the characteristic reactions of a particular compound
Functional group
A group of atoms responsible for the characteristic reactions of a particular compound. Functional group. A functional group is a specific cluster of atoms within molecules that is responsible for the characteristic chemical reactions of those molecules.

Any compound derived from a hydrocarbon by replacing at least one hydrogen atom with a halogen
Halocarbon
Any compound derived from a hydrocarbon by replacing at least one hydrogen atom with a halogen. Halocarbon. Halocarbons are chemicals that have chlorine, fluorine, bromine, or iodine atoms replacing hydrogen in hydrocarbons.

Hydrogen is added to a carbon-carbon double bond, resulting in an alkane
Hydrogenation reaction
Hydrogen is added to a carbon-carbon double bond, resulting in an alkane. Hydrogenation reaction. A hydrogenation reaction is when hydrogen is added to molecules, often turning unsaturated compounds like oils into saturated ones, like fats.

An organic compound containing a carbonyl group bonded to two carbon atoms
Ketone
An organic compound containing a carbonyl group bonded to two carbon atoms. Ketone. A ketone is a type of chemical compound where a carbon atom is double-bonded to an oxygen atom and is also connected to two other carbon atoms.

A type of organic reaction where one atom or group of atoms is replaced by another atom or group of atoms
Substitution reaction
A type of organic reaction where one atom or group of atoms is replaced by another atom or group of atoms. Substitution reaction. In simple terms, a substitution reaction is like swapping one piece of a molecule for another.
