Expert Answer

Step 1

Acidity is the ability to loose H+ (hydrogen or proton) from a molecule.

The strength of an acid is dependent upon the stability of the conjugate base formed after the loss of a hydrogen.

In the given problem, the stability of conjugate base is directly related to the resonance structures. Greater the conjugation in the system, higher will be the resonance stabilization for the anion generated in the system.

In all the cases we are studying the strength of loss of a hydrogen from -CH2- in case of 1, 2 and 3. [I will come on 4 later] 

As can be clearly seen, t...
