Problem 48P
Problem 48P
Which is a stronger base?
a. HS− or HO− c. CH3OH or CH3O− e. CH3COO− or CF3COO−
b. CH3O− or d. Cl− or Br− f. CH3CHClCOO- or CH3CHBrCOO-
Step-by-Step Solution:
Solution:
Here we have to find out which is stronger base among the given molecules.
Step 1
It is known that the relative acidity depends on the following two factors:
1. Atomic size
2.A Stronger base has weaker conjugate acid.
a. HS− or HO−
Here the bases HS- and HO- are formed from its conjugate acid H2S and H2O. Here H2S is the stronger acid than that of H2O due to the presence of S-atom, which has big atomic size than O-atom.
The conjugate base of the strong acid is less basic, thus HO- is the stronger base than HS-.
