Which of the following statements is true ?

Options

A. `CH_(3)CH_(2)S^(-)` is both a storger base and more nucleophilic than `CH_(3)CH_(2)O^(-)`
B. `CH_(3)CH_(2)S^(-)` isa dtronger base but is less nucleophilic than `CH_(3)CH_(2)O^(-)`
C. `CH_(3)CH_(2)S^(-)` is a weaker base but is more nucleophilic than `CH_(3)CH_(2)O^(-)`
D. `CH_(3)CH_(2)S^(-)` is both a weaker base and less nucleophilic than `CH_(3)CH_(2)O^(-)`

Answer

c

Explanation

`EtS^(Theta)` is weak base than `EtO^(Theta)` but more `Nu^(Theta)` rhan `etO^(Theta)` due to less solvation and more polarizability of donar 's' atom.
