Which of the following statements is true?

Options

A. `CH_3CH_2S^-` is both a stronger base and more nucleophilic than `CH_3CH_2O^-`
B. `CH_3CH_2S^-` is a stronger base but is less nucleophilic than `CH_3CH_2O^-`
C. `CH_3CH_2S^-` is a weaker base but is more nucleophilic than `CH_3CH_2O^-`
D. `CH_3CH_2S^-`is both a weaker base and less nucleophilic than `CH_3CH_2O^-`

Answer

C

Explanation

`Ets^(Theta)` is weak base than `EtO^(Theta) ` but more `Nu^(Theta)` than `EtO^(Theta)` due to less solvation and more polarizability of donar .S. atom .
