Question

Draw the structure for bromopentane. Are structural isomers possible for bromopentane?

Answer 1

The structures of bromopentane are as follows:

1)

\[\ce{CH3 - CH2 - CH2 - CH2 - CH2Br}\]

2) 

\begin{array}{cc}\\
\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\phantom{.}\\
|\phantom{....}|\phantom{....}|\phantom{....}|\phantom{....}|\phantom{.}\\
\phantom{}\ce{H - C - C - C - C - C - Br}\\
|\phantom{....}|\phantom{....}|\phantom{....}|\phantom{....}|\phantom{.}\\
\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\phantom{.}\\
\end{array}

3) 

\begin{array}{cc}\\
\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\phantom{.}\\
|\phantom{....}|\phantom{....}|\phantom{....}|\phantom{....}|\phantom{.}\\
\phantom{}\ce{H - C - C - C - C - C - H}\\
|\phantom{....}|\phantom{....}|\phantom{....}|\phantom{....}|\phantom{.}\\
\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{Br}\phantom{...}\ce{H}\\
\end{array}

4)

\begin{array}{cc}\\
\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\phantom{.}\\
|\phantom{....}|\phantom{....}|\phantom{....}|\phantom{....}|\phantom{.}\\
\phantom{}\ce{H - C - C - C - C - C - H}\\
|\phantom{....}|\phantom{....}|\phantom{....}|\phantom{....}|\phantom{.}\\
\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{Br}\phantom{...}\ce{H}\phantom{...}\ce{H}\\
\end{array}

Yes, structural isomers are possible for bromopentane. Some of its isomers are 1-bromopentane, 2-bromopentane and 3-bromopentane.
