stereochemistry #104318 - FOR OTA 104318
I need help determining the absolute stereochemistry of three molecules and an explanation as to why it is so.
C-13 NMR and GC of 3-Pentanol and 2-Pentene - a) Why is GC not able to distinguish between the trans vs. cis-2-pentene products?
b) Explain why the 3-pentanol 13C-NMR spectrum contains three peaks while the trans and cis-2-pentene spectra co ...
