Using your old and new reaction roadmaps as a guide, show how 1-bromobutane can be converted into either of the two products shown by a suitable choice of reagents. Give reagents and conditions for each reaction. (racemic) Using your old and new reaction roadmaps as a guide, show how to convert 1-bromo3-methylbutane into 2,7-dimethyloctane. You must use 1-bromo-3-methylbutane as the source of all carbon atoms in the target molecule. Show all reagents and all molecules synthesized along the way. 1-Bromo-3-methylbutane 2,7-Dimethyloctane Using your old and new reaction roadmaps as a guide, show how to convert ethane into 1-butanol. You must use ethane as the source of all carbon atoms in the target molecule. Show all reagents and all molecules synthesized along the way. Using your old and new reaction roadmaps as a guide, show how to convert 1-propanol and diiodomethane into racemic trans-1-methyl-2-propylcyclopropane. You must use 1-propanol and diiodomethane as the source of all carbon atoms in the target molecule. Show all molecules synthesized along the way. trans-1-Methyl-2-propylcyclopropane (racemic) Using your old and new reaction roadmaps as a guide, show how propene can be converted into the bis-geminal dihalocyclopropane shown. Use propene and chloroform as your main source of carbon atoms. Show all reagents and all molecules synthesized along the way
