Question: Rosmarinic acid is an antioxidant isolated from rosemary. Draw resonance structures for the radical that results from removal of the labeled H atom in rosmarinic acid.

Short Answer

Expert verified

Answer

Step by step solution

01

Rosmarinic acid

Rosmarinic acid comes under the category of polyphenol and forms a component of herbs like rosemary and basil. It can be employed as a dietary supplement or as a flavoring in food.

02

Resonance structures

Electron delocalization can be indicated by specific structures termed resonance structures. Resonance structures are responsible for imparting stability to a particular molecule.

03

 Step 3: Resonance structures that result from the removal of labeled H from rosmarinic acid

The removal of labeled H from rosmarinic acid results in the formation of a structure that can be given as:

Removal of labeled H from rosmarinic acid

The delocalization of electrons can be understood with the help of resonance structures. The resonance structures of the radical resulting from the removal of labeled hydrogen from rosmarinic acid can be given as:

Resonance structures form the radical resulted from the removal of labeled H
