Consider the molecule PF4Cl.
(a) Draw a Lewis structure for the molecule, and predict its electron-domain geometry.
(b) Which would you expect to take up more space, a P-F bond or a P-Cl bond? Explain.
(c) Predict the molecular geometry of PF4Cl.How did your answer for part (b) influence your answer here in part (c)?
(d) Would you expect the molecule to distort from its ideal electron-domain geometry? If so, how would it distort?
If a 2.490 mol quantity of NOCL was primarily placed in a 1.450 L reaction chamber at 400 C. After equilibrium was established it was found that 25.10 percent of the NOCL had dissociated. Compute the equilibrium constant Kc.
