The bigger the molecule, the
higher the boiling/melting point
And so the less flammable
they become
Very flammable
The bonds between carbon and
hydrogen atoms don't break
Empirical formula
Worked Example
Anotações:
Benzene has the molecular formula of C6H6, what is its empirical formula?
The ratio of carbon to hydrogen is 1:1, so the empirical formula would be CH.
Good for
representing ionic
compounds
Alkenes
C2H2
Unsaturated hydrocarbons
The molecules have
double covalent bonds
More reactive than alkanes
Very flammable
Burn in combustion reactions to produce
carbon dioxide and water
