IEB MATRIC CHEMISTRY DEFINITIONS
Molar Mass
The mass in grams of one mole of that substance
Solution
A homogenous mixture pf solute and solvent
Solute
The substance that is 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 if
product against the amount of product that is possible
Intramolecular bond
A bond which occurs between atoms within molecules
Covalent bond
A sharing of at least one pair of electrons by two non-metal atoms
Non-polar covalent (pure covalent)
An equal sharing of electrons
Polar covalent
An unequal sharing of electrons leading to formation of a dipole (as a result of
electronegativity difference)
Electronegativity
A measure of the tendency of an atom to attract a bonding pair of electrons
Ionic bond
A transfer of electrons and subsequent electrostatic attraction
Metallic bond
A bond between a positive kernel/cation and a sea of delocalized electrons
Intermolecular force
A weak force of attraction between molecules, ions, or atoms of noble gases
