What is the strongest base from the following weak bases?a) Ammonia NH3 (kb= 1.8x10-5)b) Hydrazine N2H2 (kb=1.7x10-7)c) Methyl amine (kb=3.6x10-4)d) Ethyl amine (kb=6.5x10-4)
Question
What is the strongest base from the following weak bases?a) Ammonia NH3 (kb= 1.8x10-5)b) Hydrazine N2H2 (kb=1.7x10-7)c) Methyl amine (kb=3.6x10-4)d) Ethyl amine (kb=6.5x10-4)
Solution
To determine the strongest base among the given weak bases, we need to compare their values of Kb (base dissociation constant). The higher the value of Kb, the stronger the base.
a) Ammonia (NH3) has a Kb value of 1.8x10^-5. b) Hydrazine (N2H2) has a Kb value of 1.7x10^-7. c) Methyl amine has a Kb value of 3.6x10^-4. d) Ethyl amine has a Kb value of 6.5x10^-4.
Comparing the Kb values, we can see that ethyl amine (d) has the highest Kb value of 6.5x10^-4. Therefore, ethyl amine is the strongest base among the given weak bases.
