(a) Interpretation: The most acidic hydrogen in the given molecule is to be predicted. Concept introduction: The most acidic proton of a molecule is removed first by a base. In a simple molecule, the acidity of a particular proton depends on the atom to which that proton is attached. In the periodic table, the acidity of HA increases across a row as the electronegativity of A increases on moving from left to right and across a column as the size of A increases on moving from top to bottom. The order of acidity is C − H < N − H < O − H < F − H .
