Using the data in the table, which of the conjugate bases below is the weakest base?

Question

Quizplus · Accepted Answer

The strength of a conjugate base is based on its ability to accept a proton. In this case, F is a highly electronegative element and will hold its lone pair of electrons tightly, making it less likely to accept a proton and therefore the weakest base. The other options all involve more electronegative atoms (Cl, O, and S) that would have a greater ability to accept a proton and are therefore stronger bases. Option E includes both O and S atoms, making it unlikely to be the weakest base.
