WitrynaTherefore, it should be clear that for cis-1,2-disubstitution, one of the substituents must be equatorial and the other axial; in the trans-isomer both may be equatorial. Because of the alternating nature of equatorial and axial bonds, the opposite relationship is true for 1,3-disubstitution (cis is all equatorial, trans is equatorial/axial). WitrynaIsomerism is a fundamental aspect of organic chemistry, and it highlights the importance of the arrangement of atoms in determining the properties and behavior of organic compounds. ... The two most common types of geometric isomers are cis-isomers and trans-isomers. In a cis-isomer, the functional groups or substituents …
