No:1 Write the transition metal containing products formed in the following reactions. Answer: a. [Mn(CO)s)- + H2C=CH-CH2CI - First product +C-O last Product b. trans-Ir(CO)CI(PPh3)2 + CH31 c. Ir(PPh3)3CI — d. (n 5 -C5Hs)Fe(CO)2(CH3) + PPh3 → e. (n 5 -C5Hs)Mo(CO)3[C(=O)CH3] → f. H3C-Mn(CO)5 + SO2 + No gas output observed No:2 Write the transition metal containing products formed in the following reactions: Answer: H3C-Mn(CO)s + P(CH3)(C6H5)2 → No gas output observed [Mn(CO)s- + (n 5 -C5H5)Fe(CO)2Br → trans-Ir(CO)CI(PPh3)2 + H2 → W(CO)6 + C6H5Lİ - cis-Re(CH3)(PEt3)(CO)4 + 13C0— (Show all expected products with their percentages) Q No:3 Write the transition metal containing products formed in the following reactions: Answer: cis-Mn(CO)4 13CO)(COCH3) ► C6H5CH2-Mn(CO)5 → Cr(CO)6+ Na/NH3 Pe(CO)s + NaCsHs → [Pe(CO)4] 2- + CH31 - H3C-Rh(PPh3)3 - CH4 + -

No 7: Rate expression of the reaction H2 + Co2(CO)82 HCO(CO)4; Velocity=k [Co2(CO)8][H2)[CO] with the equationis given. Suggest a mechanism compatible with this statement. Answer: Q No 8: Which of the following trans-complexes a) fastest b) Briefly explain the slowest reaction Cr(CO)4(PPh3)2 Cr(CO4(PPh3)(PBu3) Cr(CO)4(PPh3)[P(OMC)3] Cr(CO)4(PPh3)[P(OPn)3] Q NO 9: [Mn(CO)5]-anion reacts with 1,3-dibromopropane to give [Br-(CH2)3-Mn(CO)5] complex. However, the reaction does not stop at this step, and it reacts with the excess of [Mn(CO)5) anion creates a complex. Write the clear structure of this carbene complex and suggest a mechanism for its formation. Answer: Q NO 10 Protonation of an acyl-metal carbonyl complex [RC(=O)M(COX)]. consider easier than a metalcarbonyl or a ketone, (eg acetone).

Q NO 10 Protonation of an acyl-metal carbonyl complex [RC(=O)M(COX)]. consider easier than a metalcarbonyl or a ketone, (eg acetone). Answer: Q No 11: Show which transition metal complexes can be used to perform the following syntheses. a) Acetaldehyde from ethylene. b) From CH3CH2Cl to CH3CH2COOCH3 c) From CH3CH2C=CH2, CH3CH2CH2CH2CHO d) PhCH2CH2CH2CHO from an alkene (Ph-phenyl) Answer: No 15: One of the classic experiments in the development of the olefin metathesis was the "double cross" metathesis, in which a mixture of cyclooctene, 2- butene and 4-octene received metathesis. a) What products are expected from this metathesis? b) How do the formation of these products differ in binary and non-pair mechanisms?
