What happens when 1-butene reacts with bromine?

When 1-butene reacts with bromine, an addition reaction occurs where the bromine molecule adds across the double bond of the 1-butene molecule, resulting in the formation of 1,2-dibromobutane.


What is the name of the reaction between 1-butene and chlorine gas?

The reaction between 1-butene and chlorine gas is called chlorination. This reaction involves the substitution of a hydrogen atom in 1-butene with a chlorine atom to form a chlorinated product.


What is produce when 1-butene reacts with hcl?

When 1-butene reacts with HCl, the product formed is 2-chlorobutane. This reaction proceeds through an electrophilic addition mechanism.


How do you convert cis but 2 ene to trans but 2 ene?

To convert cis-2-butene to trans-2-butene, you can use a catalyst like palladium on carbon and hydrogen gas (H2) to perform a hydrogenation reaction. This reaction will break the double bond in cis-2-butene and reform it as trans-2-butene.


What is the reaction equation of 1-butene with sulfuric acid?

1-Butene or 2-butene on reaction with concentrated sulphuric acid produce an unstable thick oily liquid sec.butyl sulphonic acid which on dilution with water produce sec.butyl alcohol, the addition follows the Markonikov's rule.


What is the product of the chemical reaction of 2-butene and HCI?

The product of the chemical reaction between 2-butene and HCl is 2-chlorobutane. This reaction involves the addition of a hydrogen chloride molecule across the double bond of 2-butene, resulting in the formation of the chloroalkane product.


What are the compounds produced by the reaction C4H8 and HCl?

If the C4H8 compound is butene-1 or -2 or 2-methylpropene, the product is one of the chlorobutanes with general formula C4H9Cl. If the C4H8 compound is cyclobutane, there is no reaction at standard temperature and pressure.


Why concentrated acid is used in dehydration of 2-methyl-2-butanol?

2-methyl-2-butene is the major product (85%), while 2-methyl-1-butene the minor (15%) in an E1 reaction.


Mechanism of reaction between 2-butene and chloroform in presence of potassium t-butoxide?

In the reaction between 2-butene and chloroform in the presence of potassium t-butoxide, the chlorine from chloroform attacks the terminal carbon of 2-butene, resulting in the formation of a new bond between carbon and chlorine. This leads to the formation of tetrachloroethane. The potassium t-butoxide serves as a base to facilitate the reaction by abstracting a proton from the chloroform molecule.


What is the reaction equation of 2-butene with potassium permanganate?

2-butanol, CH3CH2CH(OH)CH3 + KMnO4 --------> butanone, CH3CH2COCH3 Butanol: OH | CH3-CH2-C-CH3 + KMnO4 | H Makes: Butanone: O CH3-CH2-C-CH3


What alkene could you use to prepare 2 butanol from?

You could use 1-butene to prepare 2-butanol through hydroboration-oxidation reaction. The reaction involves the addition of borane (BH3) across the double bond of 1-butene, followed by oxidation to yield 2-butanol.


What type of alcohol is formed by the hydration of 2-butene?

The hydration of 2-butene typically leads to the formation of butan-2-ol, also known as sec-butyl alcohol. This reaction involves the addition of a water molecule across the double bond of 2-butene, resulting in the formation of the alcohol.
