student placed 18.5 of glucose in a volumetric flask added enough water to dissolve the glucose by swirling then
Explain why a hydroxyl group in the para position (p-hydroxybenzoic acid, pKa=4.48) decreases the acidity while a hydroxyl group in the meta position (m-hydroxybenzoic acid, pKa=4.07) increases the acidity relative to benzoic acid (pKa=4.19).
The maximum # of stereoisomers that are possible for a given molecule can be determined from the formula, 2^n, where n is the nubmer of stereocenters in the molecule.
