How will you bring about the conversion:
glycerol to formic acid.

Explanation

To convert glycerol to formic acid, we can follow these steps:

### Step 1: Reaction of Glycerol with Oxalic Acid
Start with glycerol, which has the structure:
\[ \text{CH}_2\text{OH} - \text{CHOH} - \text{CH}_2\text{OH} \]

When glycerol reacts with oxalic acid (\( \text{C}_2\text{H}_2\text{O}_4 \)), it forms glycerol monooxalate. The reaction can be represented as:
\[ \text{Glycerol} + \text{Oxalic Acid} \rightarrow \text{Glycerol Monooxalate} + \text{H}_2\text{O} \]
