Week 10- Constitutional isomers Constitutional isomers have the same molecular formula, but their atoms are bonded in different orders. These may be further distinguished as chain isomers, which differ only in hydrocarbon chain structure, positional isomers, which differ in the location of a functional group, and functional group isomers which differ in the nature of their functional groups. Typically chain and position isomers show only modest differences in their physical and chemical properties, while functional group isomers differ greatly from...

An alternating copolymer is known to have a number-average molecular weight of 250,000 g/mol and a number-average degree of polymerization of 3406. One of the alternating mers is polystyrene which has a molecular weight of 105_g/mol. Given that the molecular weight of polypropylene is 42 g/mol and that of polyvinyl chloride is 61.5 g/mol, Which of them is the other alternating mer?

3. (10 pts) Propofol is a drug that is used for the induction of anesthesia. It is the drug that ultimately killed the singer Michael Jackson. It has the chemical formula of C12H180. It turns out that Propofol and one of its structural isomers have 13C NMR spectra that show only 6 absorbances, with two below 358 and four between 100 and 1508. Both isomers show a strong absorbance in the IR (thin film/DCM) centered around 3450 cm '; the...
