Significantly, this protocol was successfully applied to the synthesis of cis‐ and trans‐alkenes in a highly stereoselective manner in a sequential one‐pot process.doi:10.1002/adsc.201500686Krishna, JonnadaKrishna?Reddy, Alavala GopiSatyanarayana, Gedu...
2.cis– andtrans-Isomerism (Geometric Isomerism) In Alkenes cis-transisomerism is also possible for alkenes. As in small rings, rotation about pi bonds is also constrained: due to the “side-on” overlap of pi bonds,one can’t rotate a pi bond without breaking it. This stands in con...
Alkenes have double bonds; alkynes have triple bonds. ... No; a triply bonded carbon atom can form only one other bond. It would have to have two groups attached to showcis-trans isomerism. What is the difference between E and Z and cis and trans? They are the same,E- ≡ trans- ...

Alkenes like 1-butene and 2-butene exhibit constitutional isomerism, as they differ in the position of the double bond. Further, 2-butene exhibits stereoisomerism and exists as two distinct compounds differing in spatial arrangement. An isomer is calledcis-2-butene when the methyl groups are on...
Trans alkenes are MORE STABLE than their cis counterparts. This is more apparent with larger substituents. Trans Alkenes In a trans alkene, the substituents are facing away from each other. They don’t ‘get in each other’s faces’ and therefore, don’t mind the other groups. ...
β-Bromostyrene is an α,β-unsaturated aromatic halide. It can be synthesized by catalytic Hunsdiecker reaction (CHR) of cinnamic acid. It is commonly utilized as a precursor for preparing substituted alkenes, corresponding acetylenes and also in the total synthesis of natural compounds and antibio...
