Concept explainers
(a)
Interpretation:
Skeletal structure for the cis and trans isomers for 3-heptene should be drawn.
Concept Introduction:
Cis-trans isomers fall under geometric isomerism.
Cis isomers- two different groups are on the same side of the double bond.
Trans isomers- two different groups are on opposite sides of the double bond.
The skeletal structure is the arrangement of atoms and bonds in the molecule.
(b)
Interpretation:
Skeletal structure for the cis and trans isomers for 4,4-dimethyl-2-hexene should be drawn.
Concept Introduction:
Alkenes are hydrocarbon molecules that consist of a carbon-carbon double bond which has the general formula of
Cis-trans isomers fall under geometric isomerism.
Cis isomers- two different groups are on the same side of the double bond.
Trans isomers- two different groups are on opposite sides of the double bond.
The skeletal structure is the arrangement of atoms and bonds in the molecule.
