Question

Carbon disulfide (CS2) is a toxic, highly flammable substance.
The following thermodynamic data are available
for CS2(l) and CS(g)at 298 K:

(a) Draw the Lewis structure of the molecule. What do you
predict for the bond order of the C¬S bonds? (b) Use the
VSEPR method to predict the structure of the CS2 molecule.
(c) Liquid CS2 burns in O2 with a blue flame, forming
CO2(g) and SO2(g). Write a balanced equation for this reaction.
(d) Using the data in the preceding table and in Appendix
C, calculate ΔH° and ΔG° for the reaction in part (c).
