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