The number of isomeric tetraenes (NOT containing sp-hybridized carbon atoms) that can be formed from the following reaction sequence is _____ .
Answer:
2.00
Solution:
The anti-addition of hydrogen to an alkyne pi bond occurs when reacted with sodium or lithium metal dissolved in ammonia. This reaction produces a trans-alkene as its product.
Bromine react with alkene to give anti addition dibromo product. In this case both double bonds will react. In the next reaction elimination of HBr will take place forming tetraene.
The final tetraene product can show Geometrical isomerism along one double bond only. So, it will have two isomers only.
