1)Use the mechanism for the cobalt carbonyl hydride ( (HCo(CO)4 ) catalyzed hydroformylation of 1-hexene to illustrate  how  hexane  can occur as a side product . 2)Outline how Fe(CO)5  can function as a catalyst for the water gas shift reaction   ( CO + H2O ⇄ CO2 + H2 ) .

(R)-2-butanol reacts with phosphorus tribromide to give A (C4H9Br). Treatment of A with sodium cyanide in DMF gives B (C5H9)N. B is optically active. Draw the structure of B. • Use the wedge/hash bond tools to indicate stereochemistry where it exists. Show stereochemistry in a meso compound. Sn [F ? ChemDoodleⓇ

Compound A has the formula C10H16. When treated with hydrogen and palladium, Compound A takes up 1 equivalent of H2, forming Compound B. When Compound A is treated with ozone followed by zinc, Compound C forms with the formula C10H16O2. Compund C is a symmetric diketone. Provide structures for Compound A and the reaction products. Select to Draw Compound B H2, Pd/C
