Question
Rank, the following molecules in order of the acid strength, from strongest to weakest.Acetic acid pKa = 4.75Sulphuric acid pKa = 1.92Glycine carboxyl group pKa = 2.3Hydrofluoric acid = pKa 3.3Hydrochloric acid pKa = -9Glycine amine functional group pKa = 9.6
Solution
The strength of an acid is determined by its pKa value. The lower the pKa value, the stronger the acid. Therefore, the order of acid strength from strongest to weakest based on the given pKa values is:
- Hydrochloric acid (pKa = -9)
- Sulphuric acid (pKa = 1.92)
- Glycine carboxyl group (pKa = 2.3)
- Hydrofluoric acid (pKa = 3.3)
- Acetic acid (pKa = 4.75)
- Glycine amine functional group (pKa = 9.6)
