Which of the following species can act as the strongest base ?

Options

A. `.^(Θ)OH`
B. `.^(Θ)OR`
C. `.^(Θ)OC_(6)H_(5)`
D.

Answer

B

Explanation

Weakest acid has the strongest conjugate base. ROH is the acid of `RO^(-)` conjugate base, HOH is the acid of `.^(-)OH, C_(6)H_(5)OH` is the acid of `C_(6)H_(5)O^(-)` and is the acid of . Among all these acids, ROH is the weakest acid. Therefore, the strongest base is `RO^(-)` and the correct option is (b).
