5. The addition of 2,4-dinitrobenzenesulfenyl chloride to cis- and to trans-2-phenyl-2-butene gives the products shown in Equations 1 and 2, respectively. A CH CH ArSCI CH/ SAr (1) PK H CH Ph CH Ph F E SAr CH, CH H ArSCI -CH SAr 2) (2) PH CH, CH Ph CHPh. (a) What are the stereochemical relationships between the products formed? (b) Provide mechanisms for the two reactions that account for the formation of the products shown. Clearly indicate why your mechanisms account for the products formed in each reaction to the exclusion to others. 6- Derive the differential rate equation for formation of F in terms of concentrations of A, B, and D in the following mechanism, assuming that A, B, and Care in rapid equilibrium and E is a highly reactive intermediate. kt + ki K2 C + D E E k, 2E F
