The correct answer is Option E) Ch3COO-
Ch3COO- is the strongest base ion from all of the above.
What makes Ch3COO- the strongest base?
Every base mentioned here are oxobases, except option A) Cl-. It is a conjugate base of a strong acid and hence is an extremely weak base.
The presence of Cl on the other four options that is Option B), Option C) and Option D), is strongly electronegative. This pulls the oxygen non – bonding pair of electron towards oxygen and thus reduces the basicity of these electrons.
In other words, the carbonyl group and the oxygen adjacent to it withdraws the electrons and thus reduces the basicity of the non bonding pair, hence these options are cancelled.
However option E) Ch3COO- does not have any Cl groups, hence the basicity of this ion is not reduced and thus it is the strongest base.
