\[\begin{array}{cc}
\ce{CHO}\phantom{.....................}\ce{COOH}\phantom{.}\\
|\phantom{.........................}|\phantom{......}\\
\ce{(CHOH)4 + [O] ->[Br2/Water]}\ce{(CHOH)4}\\
|\phantom{.........................}|\phantom{......}\\
\phantom{.}\ce{\underset{Glucose}{CH2OH}\phantom{.................}\ce{\underset{Gluconic acid}{CH2OH}}}
\end{array}\]
