Concept Introduction:
Alkene metathesis:
An organometallic catalyzed reaction in which two alkenes exchange carbon atoms of their double bonds are said to be Alkene metathesis reaction. Two alkenes are in same molecule and the product is a cycloalkene and ring closing occurs. The catalyst used is

- Zaitsev's rule is useful in selecting which carbon adjacent to a carbocation will form the double bond in the alkene product. True or Falsearrow_forwardWhich represents an efficient synthetic route to go from an alkane to an alkene? O elimination with NaNH2, followed by a water workup O anti-Markovnikov hydrohalogenation, followed by elimination O radical bromination, followed by elimination O hydration, followed by elimination O hydration, followed by ozonolysis of the double bondarrow_forwardHow to add atoms or group of atoms to each side of an alkene, including syn and anti-addition as well as possible electrophiles that are used to react with the nucleophilic pi bond of the alkenes?arrow_forward
- Complete the following nucleophilic substitution reactions. In each reaction, show all electron pairs on both the nucleophile and the leaving group.arrow_forwardWhat starting alkene reacted with H2O and H2SO4 catalyst is required to produce 2-methylbutan-2-ol?arrow_forwardExplain addition of H2O to an alkyne ?arrow_forward
- Like other electrophiles, carbocations add to alkenes to form new carbocations, which can then undergo substitution or elimination reactions depending on the reaction conditions. With this in mind, draw a stepwise mechanism for the following reaction, which involves the addition of an electrophile—a carbocation—to a double bond.arrow_forwardDetermine the mechanism of nucleophilic substitution of attached reactionand draw the products, including stereochemistry.arrow_forward3-Hexanone can be synthesized from butanal and ethane using a Grignard reaction. The first step must be O creation of a carbocation O protonation of an oxygen nucleophilic attack of the aldehyde free radical halogenation preparation of an acetylidearrow_forward
