Arrange the following in the order of increasing acidity. List
the most acidic last.
CH3OH
CH3CO2H
CH3CH2CH2CH3
If given a table of acids and their pKas, how do you determine
which acid is stronger, especially when the table does not have the
compounds that are above listed on the table?
Here is a chart of the table given.
HCl pKa= -7. CH3CO2H pKa= 4.8. H2O pKa= 15.7. CH3CH2OH pKa= 16.
CHCH pKa= 25. H2 pKa= 35. H2NH pKa= 38. CH2CH2...
