What are the 5 reactions of alkenes?
5: Addition Reactions of Alkenes
- 5.1: Electrophilic Addition of Hydrogen Halides.
- 5.2: Addition of Strong Brønsted Acids.
- 5.3: Electrophilic Addition of Halogens to Alkenes.
- 5.4: Hydration of Alkenes.
- 5.5: Formation of alcohols from alkenes.

How do you determine if an alkene is E or Z?
If the compound contains more than one double bond, then each one is analyzed and declared to be E or Z. The configuration at the left hand double bond is E; at the right hand double bond it is Z.
What are the main reactions of alkenes?
Reactions of Alkenes
- Hydrogenation: Addition of hydrogen.
- Electrophilic addition reactions of alkenes.
- Addition of hydrogen halides.
- Halogenation: Addition of halogens.
- Addition of Water.
- Addition of sulfuric acid.
- Oxidation reactions.
- Hydroxylation: Formation of 1,2 diols.
What is the most common reaction that alkenes made?
The most common chemical reaction undergone by alkenes is the addition reaction. This reaction involves the transformation of a carbon-carbon double bond into a single bond via the addition of other functional groups.
How do you find E and Z isomers?
In the letter E, the horizontal strokes are all on the same side; in the E isomer, the higher priority groups are on opposite sides. In the letter Z, the horizontal strokes are on opposite sides; in the Z isomer, the groups are on the same side.
Can a double bond shift?
An allylic rearrangement or allylic shift is an organic reaction in which the double bond in an allyl chemical compound shifts to the next carbon atom.
Do alkenes react with electrophiles?
Electrophilic addition happens in many of the reactions of compounds containing carbon-carbon double bonds – the alkenes. We are going to start by looking at ethene, because it is the simplest molecule containing a carbon-carbon double bond.
What type of reaction is ethene and bromine?
Explanation: Ethene and bromine are an addition reaction because ethene is an alkene – it has a double bond. It is easier for new atoms to open the double bond and react there than to remove the hydrogen already attached, and then bond to it, which would be a substitution reaction.
