What are the Isomers of Pentane?
Pentane (C5H12) has three structural isomers.
Isomer 1 is
the straight chain normal structure for pentane.
Isomer 2 is
2-methylbutane, a branched chain
a carbon* atom joined onto three other carbon atoms.
Isomer 3 is
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
that each atom has, see the isomers of pentane.
