Question

Question: Which C-Hbonds in the following molecules are acidic because the resulting conjugate base is resonance stabilized?

Short answer

Answer

The most acidic C-H bonds are shown below.

Step-by-step solution

Definition of resonance

Resonance is defined as the way of representing the delocalization of pi electrons in a molecular system.It brings extra stability to the system.

Advantages of resonance

A structure that is capable of showing resonance has higher acidity as compared to those structures having no resonating structures. The hydrogen that has the highest acidity in the structure is shown below in the form of resonating structures.
