Molar mass
The mass in grams of one mole of that substance
Solution
A homogenous mixture of solute and solvent
Solute
The substance that dissolved in the solution.
Solvent
The substance in which another substance is dissolved, forming a solution.
Concentration
The amount of solute per unit volume of solution
Yield
A measure of the extent of a reaction, generally measured by comparing the amount of product against the amount of product that is possible.
Intramolecular bond
A bond which occurs between atoms within molecules.
Intermolecular force
A force of attraction between molecules, ions, or atoms of noble gases.
Covalent bond
A sharing of at least one pair of electrons by two non-metal atoms.
Non-polar covalent bond(pure covalent)
An equal sharing of electrons
Polar covalent
An unequal sharing of electrons leading to a dipole forming
Ionic bond
A transfer of electrons and subsequent electrostatic attraction
Metallic bonding
Bonding between a positive kernel and a sea of delocalised electrons.
Electronegativity
A measure of the tendency of an atom to attract a bonding pair of electrons.
Oragnic molecules
Molecules containing carbon atoms
Hydrocarbon
A compound containing only carbon and hydrogen atoms
Homologous series
A series of similar compounds which have the same functional group and have the same general formula, in which each member differs from the previous one by a single CH2 unit.
Saturated compound
A compound in which all of the bonds between carbon atoms are single bonds.
Unsaturated compound
