Glucose on reaction with \[\ce{Br2}\] water gives gluconic acid.

Explanation:

\[\begin{array}{cc}
\ce{CHO}\phantom{.............}\ce{COOH}\phantom{..}\\
|\phantom{..................}|\phantom{.......}\\
\ce{(CHOH)4 ->[Br2/H2O][(O)] (CHOH)4}\\
|\phantom{..................}|\phantom{.......}\\
\phantom{.}\ce{\underset{Glucose}{CH2OH}\phantom{.........}\ce{\underset{(Gluconic acid)}{CH2OH}}}\\
\end{array}\]
