Term
|
Definition
| A compound of hydrogen and carbon only that contains a multiple carbon-carbon bond. |
|
|
Term
|
Definition
| A bond formed by the sideways overlap of two p-orbitals, with the electron density above and the plane of the bonding atoms. |
|
|
Term
|
Definition
| A type of stereoisomerism in which different groups attached to each carbon of a C=C double bond may be arranged differently in space because of the restricted rotation of the C=C bond. |
|
|
Term
|
Definition
| stereoisomers that are non-superimposable mirror images of each other: also called 'enantiomers'. |
|
|
Term
|
Definition
| A special type of E/Z isomerism in which there are two non-hydrogen groups and two hydrogen atoms around the C=C double bond: the cis isomer (Z isomer) has H atoms on each carbon on the same side; the trans isomer (E isomer) has H atoms on each carbon on different sides. |

Term
|
Definition
| An addition reaction in which the first step is attacked by an electrophile on a region of high electron density. |
|
|
Term
|
Definition
| An atom (or group of atoms) which is attracted to an electron-rich centre or atom, where it accepts a pair of electrons to form a new covalent bond. |

Term
| Electrophilic substitution |
|
