- [Rh(PPh3)3Cl] is a precatalyst that can be activated by dissociation of a phosphine ligand to form an active catalyst, B, which is used in the hydrogenation of alkenes. The active catalyst can then undergo oxidative addition in the presence of H2 to form complex C. Propene coordinates to C to form complex D, which then undergoes a 1,2- insertion step to form E. Reductive elimination of propane from E regenerates the active catalyst B. Draw complexes B – E and hence provide a full catalytic cycle, including the activation step, for the hydrogenation of propenethe reactions listed below do not take place.Explain WHY.(for each one seperately) (DO NOT TRY TO BALANCE them , balancing is not the problem) 3Ag + H3PO4 → Ag3PO4 + 3/2 H2Propose a single synthesis method for cobalt(II) sulphate (CoSO4.7H2O) and describe in detail.
- One possible way of determining the identity of an alkene, is to let itundergo an oxidative cleavage reaction in the presence of hot basicpotassium permanganate. You are given two containers said to containdifferent alkenes. Container A is marked as cis / trans‐2‐butene andcontainer B as 2‐methyl‐1‐butene. Explain by referring to the formation ofproducts, how you would verify the identity of the alkenes.Pls ignore the highlighted part __________ is reduced in thefollowing reaction: Cr2O72- + 6S2O32-+ 14H+→ 2Cr3+ + 3S4O62- + 7H2Ocmplete the reacting by adding necessrt reagents. write in thapce provided. make sure to write regents in chemical formula . n separate regents with comma & space (ex. h2so6, h202)
