PH Scale || Reason for Acidic Character

The sequence of acidic character is

The decreasing order of acidic character is :

The decreasing order of acidic character of the following is: (I) Ph-overset(O)overset(||)(C)-NH_(2) (II) (III) PhNH_(2)

Assertion : Terminal alkynes on oxidation with Bayer's reagent give a mixture of carboxylic acid and CO_(2) Reason : Terminal alkynes show acidic character.

Assertion : Acid amides are weakly basic in nature. Reason : Basic character of acid amides is due to lone electron pair on nitrogen atom.

The decreasing order of the acidic character is : .

The weakest acid (does not show acidic character) is:

Assertion: MnO is basic whereas Mn_2O_7 is acidic. Reason: Higher the oxidation state of a transition metal in its oxide, greater is the acidic character.
