Structural isomers have the same molecular formula but a different bonding arrangement among the atoms. ... The simplest forms of stereoisomers are cis and trans isomers, both of which are created by the restricted rotation about a double bond or ring system.What...
The cis-trans isomer represents a type of steric isomerin which atoms have different spatial arrangements in threedimensional space. In the field of organic chemistry, cis isomerscontain functional groups on the same side of the carbon chainand trans isomers have functional groups on the opposite ...
