Question

Question: Triacylglycerol L yields compound M when treated with excess ${\mathit{H}}_{\mathbf{2}}$, Pd-C. Ozonolysis of L ([1] ${\mathit{O}}_{\mathbf{3}}$ ; [2] ${\left(C{H}_3\right)}_{\mathbf{2}}$ affords compounds N-P. What is the structure of L?

Step-by-Step Solution

Answer

Answer

The structure of the compound L is as shown:

Structure of L

Step 1: Hydrogenation in the presence of excess H 2 and Pd-C

The hydrogenation of alkenes, alkynes, nitro compounds, nitriles, and imines can be done using excess ${\mathit{H}}_{\mathbf{2}}$ and Pd-C. By using this reagent, the double bonds in compound L will vanish.

Step 2: Ozonolysis

The ozonolysis reaction helps detect the position of double bonds in an unknown compound based on the products formed.

The ozonolysis of compound L yields compounds N, O, and P.

Step 3:The structure of L

Based on the above structures formed by using the various reagents on L, the structure of L can be as shown below:
