Example Questions
Example Question #1 : Help With Alkene Reactions
When reacted with 1 equivalent of 
1 and 4
1 and 3
2 and 4
1, 4 and 5
2, 3 and 4
2, 3 and 4
This is a classic acid catalyzed alkene reaction. Because of resonance, several reactions have multiple products.
Example Question #2 : Help With Alkene Reactions
Which of these alkene compounds would react with hydrobromic acid 
1-Pentene
2-Butene
1-Butene
Ethene
2-Methyl-2-butene
2-Methyl-2-butene
2-Methyl-2-butene will react the fastest with hydrobromic acid because when it reacts, it will form the most stable carbocation among all of the alkenes listed. This stability allows for the reaction to proceed much quicker than other compounds, therefore it will react the fastest.
Example Question #11 : Hydrocarbon Reactants
The ozonolysis reaction involves the use of 
Ethers
Carboxylic acids
Terpenes
Esters
Aldehydes
Aldehydes
The ozonolysis of alkenes forms either ketones or aldehydes. Subsequent reagents can be added to produces alcohols and/or carboxylic acids.
Example Question #13 : Reactions By Reactant
Which of the following is an intermediate in the hydration of ethylene for the reaction given?
The reaction mechanism goes through a carbocation intermediate as follows:
Therefore the answer is the following carbocation intermediate:
Example Question #12 : Hydrocarbon Reactants
Which of the followinng sets of addition reactions proceed via syn addition?
Halohydrin addition, epoxidation
Bromination, catalytic hydrogenation
Hydroboration-oxidation, epoxidation
Bromination, epoxidation
Halohydrin addition, bromination
Hydroboration-oxidation, epoxidation
Reactions that proceed by syn addition include hydrogenation, epoxidation, and hydroboration-oxidation. Reactions that proceed by anti addition include halogenation, halohydrin addition and epoxidation followed by ring opening. Syn addition occurs because reagents must approach from only one side of the double bond.
Example Question #14 : Hydrocarbon Reactants
Predict the product of the chemical reaction given.
The reaction given is called a Markovnikov's addition reaction. This is a regiospecific reaction because only one orientation of the reaction occurs. It is an electrophilic addition reaction that involves the reaction of a halogenic acid such as 
Example Question #15 : Help With Alkene Reactions
Predict the product of the chemical reaction given.
The reaction given is called a Markovnikov's addition reaction. This is a regiospecific reaction because only one orientation of the reaction occurs. It is an electrophilic addition reaction that involves the reaction of a halogenic acid such as 
Example Question #15 : Hydrocarbon Reactants
Which of the following would be the product of the reaction given?
Molecular chlorine reacts with an alkene in the presence of water to yield a halohydrin product. Below is the mechanism for this reaction:
Example Question #17 : Help With Alkene Reactions
Which of the following would be the product of the reaction given?
Molecular bromine reacts with an alkene in the presence of water to yield a halohydrin product. Below is the mechanism for this reaction:
Example Question #544 : Organic Chemistry
What is the major product of the reaction given?
Alkenes react with NBS (N-bromosuccinimide) in the presence of light to giving products in the position next to the double called the allylic position. Below is the mechanism for this reaction:
