Answer to Question #71208 in General Chemistry for Ashley

Question

At 25 degrees Celsius and 1.00 ATM, 0.50 L of sulfur trioxide gas reacts with excess liquid sulfur dichlorvos to form liquid thionyl chloride (socl2, s is central atom) and sulfur dioxide gas.

A) and and balance the reaction

B) write the Lewis structure for sulfur trioxide, sulfur dioxide, and sulfur dichloride.
1. Determine the molecular geometries of each of the above compounds
2. Predict the IMFs expected for each compound
3.do you expect these compounds to be polar or non polar? Why?
4. Do you expect sulfur dioxide or sulfur trioxide to have a higher boiling point? Why?

Answer 1

SO3 + S2Cl2 = SO2 + SOCl2 + S

1. SO3 (triangle), S2Cl2 (gauche structure), SO2 (angle structure), SOCl2 (pyramidal structure)
2. SO3 (London dispersion forces), S2Cl2 (dipole-dipole forces), SO2 (dipole-dipole forces), SOCl2 (dipole-dipole forces)
3. SO3 (non-polar, triangle symmetry), S2Cl2 (polar, has no mirror plane perpendicular to a symmetry axis), SO2 (polar, angle symmetry), SOCl2 (polar, has no mirror plane perpendicular to a symmetry axis)
4. SO3 has higher boiling point. It possesses higher molar weight than an SO2 molecule.
