an addition reaction takes place when butene decoulourises bromine solution x
reaction of H with 1-butene
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.
2-butene gives pure Acetaldehyde while 1-butene produces a mixture of Formaldehyde and propionaldehyde.
2-butene is a covalent compound.

reaction of H with 1-butene
It called an Addition Reaction
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.
2-methyl-2-butene is the major product (85%), while 2-methyl-1-butene the minor (15%) in an E1 reaction.
Only one product is 2-chloro butane.
2-butene gives pure Acetaldehyde while 1-butene produces a mixture of Formaldehyde and propionaldehyde.
2-butene is a covalent compound.
1) Bromination: add a drop or two of dilute bromine (Br2) to the sample, if the brown color disappears, it is an alkene, and...2) Baeyer's Test: add a drop or two of potassium permanganate (KMnO4) to the sample, if the purple color disappears, it is an alkene.hope that helped! :)
1-butene has four carbon atoms.
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.
The formation of 2-methyl-2-butene from the dehydration of neopentyl alcohol involves the removal of a water molecule. Neopentyl alcohol has three hydroxyl groups, and one of them is lost during the dehydration process, resulting in the formation of 2-methyl-2-butene as the final product. This reaction typically requires the use of an acid catalyst, such as sulfuric acid.
2-butene show geomatric isomerism because each double bond carbon atom has two different group
