Given How the phosphorane required can be prepared is to be shown. A mechanism for the hydrolysis step is to be proposed. Concept introduction: Phosphoranes required for Wittig reaction are prepared by the SN 2 reaction of a primary and some secondary alkyl halides withtriphenyl phosphine followed by treatment with bases like butyl lithium in THF. To show: How the phosphorane required for the reaction can be prepared. To propose: A mechanism for the hydrolysis step.

Question

Using reaction free energy to predict equilibrium composition Consider the following equilibrium: 2NOCI (g) 2NO (g) + Cl2 (g) AGº =41. kJ Now suppose a reaction vessel is filled with 4.50 atm of nitrosyl chloride (NOCI) and 6.38 atm of chlorine (C12) at 212. °C. Answer the following questions about this system: ? rise Under these conditions, will the pressure of NOCI tend to rise or fall? x10 fall Is it possible to reverse this tendency by adding NO? In other words, if you said the pressure of NOCI will tend to rise, can that be changed to a tendency to fall by adding NO? Similarly, if you said the pressure of NOCI will tend to fall, can that be changed to a tendency to rise by adding NO? yes no If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO needed to reverse it. Round your answer to 2 significant digits. 0.035 atm ✓ G 00. 18 Ar
