MCQ
$HOCH_2·CH_2OH$ on heating with periodic acid gives
- A$2HCOOH$
- B$CHO-CHO$
- ✓$2\begin{array}{*{20}{c}}
{^H\backslash } \\
{_H/}
\end{array}C = O$ - D$2CO_2$
✓
Answer
Correct option: C.
$2\begin{array}{*{20}{c}}
{^H\backslash } \\
{_H/}
\end{array}C = O$
{^H\backslash } \\
{_H/}
\end{array}C = O$
