Concept explainers
Interpretation:
The weak bases from given list of compounds should be identified.
Concept Introduction:
Strong Base: Bases that has strong attraction towards protons and accepts readily. Strong base forms weaker conjugated acid.
Weak Base: Bases that has little affinity towards protons. Weak base forms stronger conjugated acid.
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.
