When a peroxide P is heated to 60°C in an inert solvent it decomposes by a first order process and 20% of the peroxide decomposes in 60 min. A bulk monomer is polymerized using this initiator at 60°C, the initial concentration of the letter being 4.0x10-4 mol/L. What fractions of the monomer and the initiator should remain unconverted after 10 min? At 60°C, the system parameters are k/k, = 22.34 L mol- s-, [Ans. Monomer 0.67; Initiator 0.963] %3D f = 0.8.

(76) What is the major THERMODYNAMIC product for the following reaction?
A reaction for converting ketones to lactones, called theBaeyer–Villiger reaction, is used in the manufacture of plastics and pharmaceuticals.3-Chloroperbenzoic acid is shock-sensitive, however,and prone to explode. Also, 3-chlorobenzoic acid isa waste product. An alternative process being developeduses hydrogen peroxide and a catalyst consisting of tindeposited within a solid support. The catalyst is readilyrecovered from the reaction mixture. (a) What wouldyou expect to be the other product of oxidation of theketone to lactone by hydrogen peroxide?

3. (15 points) In the Applied Organometallic Chemistry article the authors compare the relative catalytic efficiencies of the two resin-bound catalysts Pd-NHC1@M and Pd-NHC2@M in Table 1. As the mole percentage of catalyst is lowered to 0.50%, the Pd-NHC2@M catalyst is more efficient in its yield of the product of the coupling reaction shown below: Pd-NHC@M + + CO H3CO H3CO What rationale do the authors provide for the greater efficiency of Pd-NHC2@M?
