Question “Construct a three-step synthesis of trans-2-pentene from acetylene by dragging the appropriate formulas into the bins….”
Construct a three-step synthesis of trans-2-pentene from
acetylene by dragging the appropriate formulas into the bins. Note
that each bin will hold only one item, and not all of the given
reagents or structures will be used. (Me = methyl, CH3; Et = ethyl,
CH3CH2.)
Answer
This problem stems from the idea of converting acetylene into a trans alkene.
Triple bonds make Alkynes highly electronegative. They react strongly to low-electronst density chemical species. With the help of certain reaction sequences, alkynes can be transformed into many compounds.
Trans alkenes are formed when alkynes are reduced in the presence of lithium catalyst.
This is the reaction:
Triple bond proceeds are reduced as follows:
The following steps are required to form trans alkene:
Ans:
This is the correct procedure:
Conclusion
Above is the solution for “Construct a three-step synthesis of trans-2-pentene from acetylene by dragging the appropriate formulas into the bins….“. We hope that you find a good answer and gain the knowledge about this topic of science.
