1.	Electrophiles are electron seeking species. Which of the following groups contain only electrophiles ?
Answer» `BF_(3), NH_(3), H_(2)O` `AlCl_(3), SO_(3), NO_(2)^(+)` `NO_(2)^(+), CH_(3)^(+), CH_(3)-overset(+)(C) = O` `C_(2)H_(5)^(-), overset()(C_(2))H_(5), C_(2)H_(5)^(+)` SOLUTION :(B) `AlCl_(3), SO_(3), overset(+)(N)O_(2)` and `NO_(2)^(+), overset(+)(C)H_(3), CH_(3)-overset(+)(C) = O`. In OPTION (a), `NH_(3)` and `H_(2)O` are nucleophiles whereas `BF_(3)` is an ELECTROPHILIC while in option (d) `C_(2)H_(5)^(-)` is a nucleophile while `overset()(C_(2))H_(5)` and `C_(2)H_(5)^(+)` are electrophiles.
