Chemistry Definitions Module 4.1.2

A compound containing carbon and hydrogen atoms joined in straight or branched chains or in non-aromatic rings

An aliphatic compound that is arranged in non-aromatic rings

A homologous series with general formula CnH2n+2

A group with the general formula CnH2n+1

An organic compound containing a benzene ring

Shows the movement of a pair of electrons. Curly arrows must start from a bond, a lone pair of electrons or a negative change

A partial charge on an atom which is caused by the differing electronegativities of atoms in a covalent bond

The relative positions of atoms and the bonds between them

A group of atoms responsible for the characteristic reactions of a compound

The simplest algebraic formula of a member of a homologous series

A series of organic compounds containing the same functional group with successive members differing by -CH2

The simplest whole number ratio of atoms of each element present in a compound

An organic compound which only contains C-C single bonds

When a covalent bond breaks, one bonding atom receives both electrons from the bonded pair

When a covalent bond breaks, each bonding atom receives one electron from the bonding pair, forming 2 radicals

International Union of Pure and Applied Chemistry

The number and type of atoms of each element in a molecule

The naming system for compounds

A carbon-containing compound

A species with an unpaired electron

A series of steps that represent the overall reaction by showing the breaking and forming of bonds using curly arrows

The simplified organic formula, shown by removing hydrogen atoms from alkyl chains, leaving the carbon skeleton and the functional groups

The minimal detail that shows the arrangement of atoms in a molecule

Compounds with the same molecular formula but different structural formulae
