Electrophiles are electron seeking species. Which of the following groups contain only electrophiles ?

Options

A. `BF_(3), NH_(3), H_2 O`
B. `AICI_(3), SO_(3), NO_(2)^(+)`
C. `NO_(2)^(+), CH_(3)^(+), CH_(3) - overset(+) = O`
D. `C_(2) H_(5)^(-), overset(+)C_(2) H_(5), C_(2) H_(5)^(+)`

Answer

B, C

Explanation

In (a) `NH_3 and H_2 O` are nucleophiles but `BF_3` is electrophile. In `(d) C_2 H_6(-)` is nucleophile but `overset(+) C_2 H_5 and C_2 H_6^(+)` are electrophiles.
