The two most common (and useful) nuclei detected by NMR are 1 H (i.e. hydrogen atoms) and 1 3 C (i.e. carbon atoms). In this experiment, you will perform a selective hydroboration/oxidation reaction of indene, and use 1 3 C NMR to determine the structure of your product.

Vanillyl alcohol ir spectrum keyword after analyzing the system lists the list of keywords related and the list of websites with related content, in addition you can see which keywords most interested customers on the this website Because isoborneol is more stable, it is going to be the major product. This can be calculated by using the integration of the corresponding peaks on the H-NMR graph. This calculation is shown in the results section. The molar ratio of the product was 88.42% isoborneol and 11.58% borneol. Another analysis of the product was done by melting point.

Could you unambiguously distinguish between borneol and isoborneol using 13C NMR spectroscopy? If not, why not? they both only have 10 peaks, so I'm kinda confused For information, the entry in Purification of Laboratory Chemicals suggests recrystallising from ethanol or petroleum ether, melting point data is also provided as a way of assaying the resulting material (though NMR would be better). dl-Isoborneol [124-76-5] M 154.3, m 212° (sealed tube).
