Volatility
The ease that a liquid turns into a gas. Volatility increases as boiling point decreases
1 of 13
Esterification
The reaction of an alcohol with a carboxylic acid to produce an ester and water
2 of 13
Dehydration
An elimination reaction in which water is removed from a saturated molecule to make an unsaturated molecule
3 of 13
Hydrolysis
A reaction with water or aqueous hydroxide ions that breaks a chemical compound into two compounds
4 of 13
Nucleophilic Substitution
A type of substitution reaction in which a nucleophile is attracted to an electron-deficient centre or atom, where is donates a pair of electrons to form a new covalent bond
5 of 13
% Yield
actual amount, in mol, of product / theoretical amount, in mol, of product x 100
6 of 13
Limiting Reagent
The substance in a chemical reagent that runs out first
7 of 13
Atom Economy
molecular mass of the desired product / sum of molecular masses of all products x 100
8 of 13
