Why does SO 3 act as an electrophile?

Options

  1. ABecause it has a high electron density due to the presence of lone pairs on sulphur.
  2. BBecause it has a negative charge on sulphur, making it electron-deficient.
  3. CThree highly electronegative oxygen atoms are attached to sulphur atom. It makes sulphur atom electron deficie
  4. DBecause it has a highly non-polar covalent bond between sulphur and oxygen.

Correct answer

C. Three highly electronegative oxygen atoms are attached to sulphur atom. It makes sulphur atom electron deficie

Step-by-step solution

Correct Option is : (C) Three highly electronegative oxygen atoms are attached to sulphur atom. It makes sulphur atom electron deficient. Due to resonance also, sulphur acquires positive charge. Both these factors make SO 3 an electrophile.
