Rank the following compounds in order of increasing acidity. ΝΗ ΝΗ ΝΗ

Identify and explain the most acidic proton on the following molecule.

Rank the following compounds in their correct order of acidity. 1=Most acidic and 4=least acidic.

4-Methylphenol is more acidic than ethanol (pKa 10.36 vs 16.0) , even though both contain an OH group and a methyl group. Draw the structures of the anions formed from loss of the alcoholic protons from both compounds. Use resonance to explain the difference in their respective acidities.

Rank the following compounds in order of increasing acidity (1 = least acidic, 3 = most acidic) and in the space provided use resonance (of the conjugate base) to explain why the compound you have labelled “3” is the most acidic.
