Cis and trans isomerization
Web9 years ago. Alkenes are usually named using cis/trans or E/Z. Syn and anti are reserved to indicate the geometry of addition across a double bond when it undergoes reactions: if two atoms add from the same side of the double bond then it is called syn, and if they add from opposite sides of the double bond, then it is called anti addition. WebThe two isomers can be switched with particular wavelengths of light: ultraviolet light, which corresponds to the energy gap of the π-π* (S 2 state) transition, for trans-to-cis conversion, and blue light, which is equivalent to that of the n-π* (S 1 …
