Step 1

Structure B is more stable because the negative charge is delocalized over the benzene ring, which is more electronegative than the nitrogen atom. Show more…

00:01 Dear friends, this is the compound given.

00:03 Now here we are having four hydrogen, four different types of hydrogen atoms, ha, hb, hc, and hd.

00:11 Now these hydrogens, we have to arrange them in the increasing order of their acidity.

00:18 Increasing order of their acidity.

00:22 Now, acidic hydrogen will be more acidic if it is attached to a more electromagnetic atom like oxygen, sulfur, nitrogen.

00:32 Here here the four hydrogen atoms two are attached to nitrogen and one is to oxygen and one is to sulfur now after the removal of hydrogen if the atom is able to bear the negative charge properly then the hydrogen can easily be replaced and the compound will become the heart it will become acidic in nature now if we compare oxygen sulfur and nitrogen sulfur is the large one sulfur and oxygen let us compare, then size of sulfur is large.

01:10 So can bear negative charge easily.

01:18 Therefore, hc will be the most acidic one.

01:22 Hc is the most acidic one.

01:28 Then comes the hydrogen attached to oxygen.

01:34 This one, oxygen is more related to negative than nitrogen.

01:37 Therefore, this hydrogen is more acidic.

01:39 Again, these are attached to the benzene ring.

01:42 So, negative charge is more stable than oxygen and sulfur.

01:45 But in nitrogen, here, there is no conjugation is there.

01:49 Here, conjugation is there.

01:51 So that's why negative charge is more stable on oxygen and sulfur...
