Electrons that are shared between one or more electrons
2 of 13
Addition reaction
A reaction in which a reactant is added to an unsaturated molecule to make a saturated molecule.
3 of 13
Substitution reaction
A reaction in which an atom or group of atoms is replaced by a different atom or group of atoms
4 of 13
Electrophile
An atom or group of atoms that is attracted to an electron rich centre where it accepts a pair of electrons and forms a new covalent bond
5 of 13
Electrophilic substitution
a type of substitution reaction in which an electrophile is attracted to an electron rich centre of atom, where it accepts a pair of electrons to form a new covalent bond
6 of 13
Reaction mechanism
a series of steps that together make up the overall reaction
7 of 13
Reflux
the continual boiling and condensing of a reaction mixture to ensure the reaction takes place without the contents of the flask boiling dry
8 of 13
Nucleophile
A atom or group of atoms attracted to an electron-dificient centre where it donates a pair of electrons to form a new covalent bond
9 of 13
Esterification
The reaction of an alcohol with a carboxlyic acid to produce an ester and water
10 of 13
Hydrolysis
A reaction with water of hydroxide ions that breaks a compound into two compounds
