The compounds have the same molecular mass. How can you use mass spectrometry to distinguish them. Draw two of the possible ions that results when the molecular ion of the following either undergoes fragmentation by a cleavage. Use the synthesis of Williamson to prepare the following ether
label each major peak with a molecular formula (including charge) label the molecular ion peak as "M+" (if present) label major peaks other than the molecular ion with three things: 1) the mass to charge ratio 2) the structure or formula for that charged fragment 3) another formula to show which fragment was lost by the molecular ion to form that ion Mass spec NEUTRAL COMPOUND 100- 80 2-6utanene 60 40 20- 75 60 65 70 35 40 45 10...
Name: Starting with the mass spectrum of n-heptane What is the molecular ion? What fragment is lost to generate the ion with m/z =71? What cation does the peak at m/z = 43 represent? What group does the spacing between each set of ions represent? Why is the peak at (M-15), corresponding to loss of -CH3 so small? Draw the structure of 2,4-dimethylpentane What is the structure of the ion responsible for m/z = 85? Relative Intensity What is the...
