Write the structure of different isomeric alkanes corresponding to the molecular formula `C_(6)H_(14)`. Also give their `IUPAC` names.
Strategy: Start with the longest contionous chain with no branching and go on increasing the number of branching by removing one, two, etc, `C` atoms from the longest chain and reattaching them, but do not attach them to the terminal `C` atoms.

`underset(3-" Methylpentane")(CH_(3)CH_(2)overset(CH_(3))overset(|)(C)HCH_(2)CH_(3))" "underset(2,2-" Demthylbutane")(CH_(3)underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)HCH_(2)CH_(3))`
