Question: answer EACH problem please! 1 2 3 4 5 Consider the expected splitting of signal b in the 1H NMR spectrum of 1-methoxy-2methylpropane, shown below.




Consider the expected splitting of signal "b" in the 1H NMR spectrum of 1-methoxy-2methylpropane, shown below. Presuming that Jab is sufficiently different from Jbc and that the instrument has sufficient resolving power, what is the theoretical multiplicity of signal "b"? 12 8 9 21 24 In the structure shown, Hb and Hc are classified as: diastereotopic protons. homotopic protons. geminal protons. isomeric protons. enantiotopic protons. For the following compound how many different signals would you see in the carbon NMR? (Assume that you can see them all.) 4 5 3 9 The 1H NMR spectrum of which of the compounds below, all of formula C7H12O2, would I II consist of two singlets only? What is the structure of the compound in the following 1HNMR spectrum with the molecular formula C6H12O2 ? Relative integration is shown
