There can be 3 possible isomers for an alkane having formula C₅H₁₂. These are as follows:

\[\begin{array}{cc}
\phantom{.............}\ce{CH3}\\
\phantom{...........}|\\
\ce{CH3\underset{\text{n-pentane}}{CH2CH2CH2}CH3, CH3 - \underset{\text{lsopentane}}{CH - CH2} - CH3},
\end{array}\]

\[\begin{array}{cc}
\phantom{...}\ce{CH3}\\
|\\
\ce{CH3 - C - CH3}\\
|\\
\phantom{......}\ce{\underset{\text{Neopentane}}{CH3}}
\end{array}\]
