1.    Draw the structure of cetyl myristate, a minor component of spermaceti wax, formed from a 14-carbon fatty acid and a 16-carbon straight chain alcohol. 

State the type of isomerism present in alkene with formula C4H8

Dextroamphetamine is an example of a chiral drug that has been shown to be more effective than its enantiomer Levoamphetamine. Given the active enantiomer below, assign priorities to the CH₃, CH₂, NH₂ and H, and do an RS assignment. How would you distinguish the enantiomers that are present in a sample? How would you determine the % purity? Dextroamphetamine undergoes racemisation, explain the clinical significance of racemisation

Different enantiomers are metabolised differently by the body. The monosaccharide below has been patented proposed as a low-calorie sweetener. Do a D and L assignment for the enantiomer below, explain your assignment and how this would affect the calorific value of the rhamnose isomer. Provide an explanation for the following:

1.    Would the monosaccharides below more likely adopt a pyranose or furanose?

2.    Is the sugar considered a reducing sugar?

3.    Would the optical rotation of the enantiomer below change in the solution?
