Question

how to find acidity order? can anyone explain it with examples

Answer 1

Your organic teachers are quite likely to ask you questions like identify the most acidic protons or the most basic site in a molecule.  These facts can be important for determining where a molecule is likely to react when treated with a base or acid respectively. Many students can not do this efficiently. The following topics are covered here:

Definitions : Arrenhius, Bronsted, Lewis

Acidity :  Ka and pKa

Common acids in organic chemistry

Basicity

Common bases in organic chemistry

Remember that acidity and basicity are the based on the same chemical reaction (but looking at it from opposite sides) and both happen simultaneously. In the following simple example the base, B, removes a proton from the acid, H-A:

Answer 2

By checking it’s ph value with the help of ph scale . If the ph value is 7 the given solution is basic . The reading between 0 to 6 indicates acid . If we will go in decreasing order of numbers more strong the acid will . The acid which has ph value 0 on the scale is most acidic . ( dark red colour of scale at that point indicates it )
