a.

or

b.

or

Short Answer

Expert verified

a. Ethanol is a stronger compound.

b. Phenol is a stronger compound.

Step by step solution

01

Acids

Acids take part in numerous reactions in chemistry. They can be strong or weak and their definition varies as per the theories provided.

Hydrogen ions are liberated when acids are in contact with water which is an important characteristic of acid.

02

Comparison of compounds in a

The pKa values of propane and ethanol are 50 and 16, respectively. The compound with a lower pKavalue is a stronger acid.

As ethanol has a lower pKavalue than propane, it is a stronger acid.

03

Comparison of compounds in b

The Ka values of phenol and toluene are 10-10 and 10-41 , respectively. The compound with a higher Ka value is a strong acid.

As phenol has a higher Kavalue than toluene, it is a stronger acid.
