Concept explainers
Interpretation:
Given acid-base reaction has to be completed and the direction of equilibrium has to be predicted.
Concept introduction:
According to the explanations by Bronsted-Lowry, if a species loses a proton then it is an acid whereas if a species receives one proton, then it is base.
If a base receives one proton, then the formed species is a conjugate acid whereas an acid lose one proton, then the formed species is a conjugated base.
Weak acids are more stable and less reactive, so equilibrium follows the direction of formation weak acids in a reaction.

- Quinuclidine and triethylamine are both tertiary amines. Quinuclidine, however, is a considerably stronger base than triethylamine. Stated alternatively, the con- jugate acid of quinuclidine is a considerably weaker acid than the conjugate acid of triethylamine. Quinuclidine pK, 10.6 Triethylamine pK, 8.6 Propose an explanation for these differences in acidity/basicity.arrow_forwardIndicate the following statement as true/false. 1) While ethylamine is soluble in water, pentylamine is insoluble in water. Right False 2)When amines are reacted with bases, they form ammonium salts. right false 3) Aliphatic amines are more basic than ammonia, whereas aromatic amines are less basic than ammonia.
