Are the amines with large PKb values strong bases? true or false
Homework Answers
FALSE
Explanation
The amines have large pKb values means the Kb of amine is lesser
and the dissociation of amines are lesser. Thus, amine will be
weaker base. It means that the amines with higher the pKb values
are weak bases not strong base.
