Question

Which of the following pairs represent electrophiles? (A) AlCl3 , H2O (B) SO3 , NO2+ (C) BF3 , H2O (D) NH3 , SO3

Tardigrade Admin · Accepted Answer

Electrophiles are electron deficient or positively charged species. In SO 3, oxygen is more electronegative than sulphur and therefore can withdraw electron density towards themselves, creating positive charge on sulphur atom, hence SO 3 becomes electron deficient and can act as a electrophile.
