This compound only contains covalent bonds, more descriptively, one double bond and all others are single bonds.
Double bond
2-butene gives pure Acetaldehyde while 1-butene produces a mixture of Formaldehyde and propionaldehyde.
reaction of H with 1-butene
The C2 carbon of 2-methyl-1-butene is an sp2 configuration: It is connected to a methyl group and to the rest of the skeleton chain. There is a dipole generated from both of the sp3 carbons towards the C2 carbon, mainly due to the difference in sigma bond strengths. Sigma bonds are stronger than pi bonds, making it slightly more electron pulling. So, having a higher "s" character in sp2 (33% s) will pull dipoles of sp3 (25% s). There is no dipole generated between a hydrogen and an sp2 carbon. The net dipole strength is therefore stronger in 2-methyl-1-butene than 1-pentene. Since boiling points depend on dipole and London forces, 2-methyl-1-butene will bind better to each other than 1-pentene, thus will have a higher boiling point.
Organic compounds with double bonds are classified as alkenes, and end with the suffix -ene, such as pentene or butene. Compounds with triple bonds are called alkynes, and end with -yne, such as octyne or propyne.
Hexene, C6H12, contains single bonds and 1 double bond
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! :)
2-butene gives pure Acetaldehyde while 1-butene produces a mixture of Formaldehyde and propionaldehyde.
reaction of H with 1-butene
1-butene has four carbon atoms.
1-butene 2-butene di-n-butyl ether
2-methyl-2-butene is the major product (85%), while 2-methyl-1-butene the minor (15%) in an E1 reaction.
2-butene show geomatric isomerism because each double bond carbon atom has two different group

Organic compounds with double bonds are classified as alkenes, and end with the suffix -ene, such as pentene or butene. Compounds with triple bonds are called alkynes, and end with -yne, such as octyne or propyne.
This question is ambiguous, because double bonds do not occur "in" a particular carbon atom but between 2 carbon atoms. If the chain is straight and the double bond occurs between the second and third atoms counting from one end of the chain, the name of the compound is butene-2, 2-butene, or but-2-ene. If the double bond occurs between the third and fourth atoms counting from one end of the chain,the name of the compound is butene-1, 1-butene, or but-1-ene. (Numbers in a hydrocarbon chain are selected so as to use the smaller number consistent with actual structure, irrespective of the end from which the counting is started.)
