Electronegativity

A measure of the attraction of a bonded atom for the pair of electrons in a covalent bond

1 of 9

Instantaneous dipole- Induced dipole

Where a molecule with an instaneous dipole (Uneven electron density distribution at any one time forming a partially charged molecule) induces a dipole in a neighbouring molecule forming an intermolecular bond

2 of 9

Permanent dipole -Permanent dipole

When two molecules with permanent dipoles (Two atoms bonded to each other with sufficient differences in electro negativities causing permanent partial charges on the molecules) are attracted to each other and form an intermolecular bond.

3 of 9

(First) Ionisation enthalpy

The energy required to remove one electron from each atom in 1 mole of gaseous atoms to form 1 mole of gaseous 1+ ions

4 of 9

Hyrolysis

The breaking of bonds with the addition of water

5 of 9

Substitution reaction

A reaction in which an atom or group of atoms is replaced with different atoms or groups of atoms.

6 of 9

Nucelophile

A molecule or negatively charged Ion with a lone pair of electrons that it can donate to a positively charged atom to form a new covalent bond

7 of 9

The loss of electrons

8 of 9
