Answer to Problem 10.1P
The structure of six alkenes having molecular formula
Explanation of Solution
The given molecular formula of the compound is
The first possible structure of alkene with molecular formula
Figure 1
The first possible structure of alkene contains five carbon and ten hydrogen atoms. The double bond is present between first and second carbon atom.
The second possible structure of alkene with molecular formula
Figure 2
The second possible structure of alkene contains five carbon and ten hydrogen atoms. The double bond is present between first and second carbon atom. One methyl substituent is attached to the second carbon atom.
The third possible structure of alkene with molecular formula
Figure 3
The third possible structure of alkene contains five carbon and ten hydrogen atoms. The double bond is present between first and second carbon atom. One methyl substituent is attached to the third carbon atom.
The fourth possible structure of alkene with molecular formula
Figure 4
The fourth possible structure of alkene contains five carbon and ten hydrogen atoms. The double bond is present between second and third carbon atom. One methyl substituent is attached to the second carbon atom.
The fifth possible structure of alkene with molecular formula
Figure 5
The fifth possible structure of alkene contains five carbon and ten hydrogen atoms. The double bond is present between second and third carbon atom. Substituents attached to the second and third carbon atom are on different side.
The sixth possible structure of alkene with molecular formula
Figure 6
The sixth possible structure of alkene contains five carbon and ten hydrogen atoms. The double bond is present between second and third carbon atom. Substituents attached to the second and third carbon atom are on same side.
A pair of diastereomers exists when two substituents attached to each of the double bonded carbon atoms are different. The fifth and sixth structure indicates that the substituents bonded to the
Therefore, a pair of disatereomers is shown below.
