Question

Match each compound with its appropriate pKa value.

(a) 4-Nitrobenzoic acid, benzoic acid, 4-chlorobenzoic acid pKa=4.19,3.98, and 3.41pKa =4.19,3.98, and 3.41
(b) Benzoic acid, cyclohexanol, phenol pKa=18.0,9.95, and 4.19pK a =18.0,9.95, and 4.19
(c) 4-Nitrobenzoic acid, 4-nitrophenol, 4-nitrophenylacetic acid pKa=7.15,3.85, and 3.41pK a =7.15,3.85, and 3.41

Answer 1

Step-by-step explanation:

a) 4-nitrobenzoic acid pKa= 3.41

benzoic acid pKa= 4.19

4-chlorobenzoic acid pKa= 3.98

b) benzoic acid pKa= 4.19

cyclohexanol pKa= 18.0

phenol pKa= 9.95

c) 4-Nitrobenzoic acid pKa= 3.41

4-nitrophenol pKa= 7.15

4-nitrophenylacetic acid pKa= 3.85
