- The following pKa values have been measured. Explain why a hydroxyl group in the para position decreases the acidity while a hydroxyl group in the meta position increases the acidity.arrow_forwardCalculate the Ka's for the following acids: (a) Citric acid, pKa = 3.14 (b) Tartaric acid, pKa = 2.98arrow_forwardThe Ka for dichloroacetic acid is 3.32 Ă— 10-2. Approximately what percentage of the acid is dissociated in a 0.10 M aqueous solution?arrow_forward
- Identify the reagents a–c in the following scheme:arrow_forwardIdentify all the acidic hydrogens (pKa 25) in the following molecules:arrow_forwardThe pKa of p-cyclopropylbenzoic acid is 4.45. Is cyclopropylbenzene likely to be more reactive or less reactive than benzene toward electrophilic bromination? Explain.arrow_forward
