Calculate the percent yield if you start with 0.220 mL trans-cinnamaldeyde and 0.6643 g benzyltriphenylphosphonium chloride in 1.5 mL 10 N NaOH and isolate 0.2137 g 1,4- diphenyl-1,3-butadiene. Show ALL your calculations! (3 points) (Hint: first you need to compare the moles of the substrates to know which substrate is the limited reagent. Then you calculate the percent yield by comparing the moles of the product with the theoretical yield (moles of the limited reagent).

Suppose 18.3 g of sodium iodide is dissolved in 300 mL of a 0.30 Maqueous solution of silver nitrate. Calculate the final molarity of iodide anion in the solution. You can assume the volume of the solution doesn't change when the sodium iodide is dissolved in it. Be sure your answer has the correct number of significant digits. X 52

NUCLEOPHILIC DISPLACEMENT- FORMATION OF AN ETHER BY AN SN2 REACTION Bond formation by use of an SN2 reaction is very important for organic and biological synthesis. Many new bonds formed make use of this versatile reaction pathway. In this reaction, one partner is the nucleophile and the other partner is the electrophile. The electrophile will have a leaving group that will be lost in the reaction. In the SN2...

1. In both the sodium iodide
test and the silver nitrate test, why does 2-bromobutane react
faster than 2-chlorobutane?
Bromine is a better leaving group since it is a weaker base than
chlorine is.
2. a. Why does benzyl chloride react under both
SN1 and SN2 conditions?
Benzyl
chloride is a primary alkyl halide, hence reactive under SN2
conditions.
The
primary carbocation formed due to the departure of Cl- is
stabilized by the pi electrons in the benzene ring.
b. Why is...
