Cis and trans orgo
WebFor vinylic hydrogens in a trans configuration, we see coupling constants in the range of 3 J = 11-18 Hz, while cis hydrogens couple in the 3 J = 6-15 Hz range. The 2-bond coupling between hydrogens bound to the same alkene carbon (referred to as geminal hydrogens) is very fine, generally 5 Hz or lower. WebCis-trans isomers have different physical, chemical, and physiological properties. Cis -2-butene has both methyl groups on the same side of the molecule. Trans -2-butene has …
