Arrange these acids in terms of increasing acidity:

Question

CH3COOH, NH3+CH2COOH, CH3CONHCH2COOH

My answer is CH3COOH,CH3CONHCH2COOH,NH3+CH2COOH .

Is this correct Dr.Bob?

Answer 1

It appears to me that you have them reversed.

Answer 2

But Dr.Bob,from what I refer,NH3+CH2COOH is the strongest acid since it has both acid and NH3 protonated.Acetic acid is a weak acid,I'm not sure about the CH3CONHCH2COOH. That's what confuses me
