Calculated the Molecular Formula based on (2) ® actual no of atoms in molecule
= Mass of
Empirical formula x N {integer}
(3) Carried out qualitative chemical tests to
get an indication of the functional groups – we will do this in
a Practical session.
(4)

DE = hn absorption of radiation leads to a change in the
energy states of a molecule.
