Delocalised Electrons
Electrons that shared between more than two atoms.
1 of 16
Addition Reaction
A reaction in which a reactant is added to an unsaturated molecule to make a saturated molecule.
2 of 16
Substitution Reaction
A reaction in which an atom or group of atoms is replaced with a different atom or group of atoms.
3 of 16
Electrophile
An atom (or group of atoms) which is attracted to an electron-rich centre or atom, where it accepts a pair of electrons to from a new covalent bond.
4 of 16
Nucleophile
An atom (or group of atoms) which is attracted to an electron-deficient centre or atom, where it donates a pair of electrons to form a new covalent bond.
5 of 16
Electrophilic Substitution
A type of substitution reaction in which an electrophile is attracted to an electron-rich centre or atom, where it accepts a pair of electrons to form a new covalent bond.
6 of 16
Reaction Mechanism
A series of steps that, together, make up the overall reaction.
7 of 16
Curly Arrow
A symbol used in reaction mechanisms to show the movement of an electron pair in the breaking or formation of covalent bonds.
8 of 16
Functional Group
The part of an organic molecule responsible for its chemical reactions.
9 of 16
Electronegativity
A measure of the attraction of a bonded for the pair of electrons in a covalent bond.
10 of 16
Redox Reaction
One in which both reduction and oxidation take place.
11 of 16
Reflux
The continual boiling and condensing of a reaction mixture to ensure that the reaction takes place without the contents of the flask boiling dry.
12 of 16
Esterification
The reaction of an alcohol with a carboxylic acid to produce an ester and water.
13 of 16
Hydrolysis
A reaction with water or hydroxide ions that breaks a chemical compound into two compounds.
14 of 16
Low-Density Lipoprotein (LDL)
A type of lipoprotein responsible for carrying cholesterol and triglycerides from the liver to the tissues.
15 of 16
High-Density Lipoprotein (HDL)
A type of lipoprotein that can remove cholesterol from the arteries and transport it back to the liver for excretion or re-utilisation.
