Would you expect the E or Z isomer of the alkene product to be more stable? What is your reason for this prediction?Based on your proton NMR spectrum and yields, which alkene (E vs. Z) was the major product of this reaction? What was the percentage E vs. Z-alkene in your product?

Would you expect the E or Z isomer of the alkene product to be more stable? What is your reason for this prediction?

What is the % yield of your product? Show your calculations! Note: consider which
reactant was the limiting reagent.

Interpret the IR spectrum of your isolated product. Assign peaks to the functional groups present in the product.

Interpret the proton NMR spectra of your isolated products. Were you able to obtain the pure E and pure Z isomers of DMANS?

Based on your proton NMR spectrum and yields, which alkene (E vs. Z) was the major product of this reaction? What was the percentage E vs. Z-alkene in your product?

In your opinion, do you think this is a stereoselective reaction (e.g., it favors one stereoisomer of the product over another stereoisomer)? Is the reaction stereospecific (e.g., it forms only one stereoisomer of the product)?
