Most Acidic Hydrogen - Ex. 1

Identify which hydrogen ion in the following molecule is the most acidic.

-- ignore hydrogens attached to carbons

-- expand the hydrogens attached to heteroatoms

-- heteroatoms = non-carbon atoms

-- there are no formal charges on P, S, or N

-- use the acidity trend

-- this states that more acidic hydrogens are bonded to atoms down and to the right on the periodic table

-- between P, S, and N, S is the furthest down and to the right

-- this means the hydrogen connected to S is the most acidic hydrogen
