Isomers of Pentane.
Pentane (C5H12) has three structural isomers.
Isomer 1 is
n-pentane, the straight chain normal structure for pentane.
Isomer 2 is
2-methylbutane, a branched chain
with a carbon* atom
joined onto
three other carbon atoms.
Isomer 3 is
2,2-dimethylpropane, a
branched
chain with the central carbon* atom
joined onto
four other carbon atoms.
Note that for all the isomers, each
carbon atom has four bonds (valency
4),
and each hydrogen atom has one bond
(valency 1).
Valency is the combining power of an atom.
You cannot change the number of
bonds which each
atom has, see next
page.
