U is the anhydride of sulphuric acid, obtained by dehydrating oleum. It reacts as : U + H₂O → H₂SO₄ ; U + HCl → X (chlorosulphuric acid) ; U + NH₃ → (NH₄)₂SO₄ (excess NH₃). The O-S-O bond angle in gaseous U is θ°. The value of θ is :
Answer:
120
Solution:
SO₃(g) is trigonal planar (sp²), so the O-S-O bond angle is 120°.
