Which is the cis isomer of 1, 2-diphenylethene?
cis isomers of 1,2-diphenylethene, more commonly known as trans- and cis-stilbene. H H H H trans-stilbene cis-stilbene m.p. 122-124°C b.p. 82-84°C density 0.970 g/mL density 1.011 g/mL M.W. 180.25 g/mol M.W. 180.25 g/mol In both cases, the nucleophilic double bond undergoes an electrophilic addition reaction
How are cis and trans isomers of stilbene different?
Since the cis and trans isomers of stilbene have different geometries, it follows that upon reaction with bromine they give rise to stereoisomeric bromonium ions and, eventually, products that differ only by their stereochemistry. The product of this reaction, 1,2-dibromo-1,2-diphenylethane, has two stereogenic
What is the density of bromine in stilbene?
H H H H. trans-stilbene cis-stilbene m.p. 122-124°C b.p. 82-84°C density 0.970 g/mL density 1.011 g/mL M.W. 180.25 g/mol M.W. 180.25 g/mol In both cases, the nucleophilic double bond undergoes an electrophilic addition reaction by the bromine reagent which proceeds via a cyclic bromonium ion.
