E and z cis and trans
WebIn general terms there is NO specific relationship between cis and trans / E and Z as they are based on fundamentally different naming rules. 1,2-disubstituted alkenes are described as: cis - if the two alkyl groups, R-, that form the longest chain ( i.e. the root name) are on the same side of the C=C. trans - if the two alkyl groups, R-, that ... WebCis isomers are molecules with the same connectivity of atoms. They feature same side groups placed on the same side of a double bond. Trans isomers feature molecules with same side groups placed on opposite sides of a double bond. Cis isomers are almost always polar. Trans isomers are not very polar. Many trans isomers are non-polar …
