Concept explainers
(a)
Interpretation:
The structure of cis-2-octene should be drawn.
Concept Introduction:
The rotation around the carbon atoms of a double bond is restricted. So, groups on one side of the double bond cannot rotate to the other side. Depending on the side of the alkyl group attached to the double bond, there are two stereoisomers as cis and trans. Trans indicates that the alkyl groups are on opposing sides and cis indicates that the alkyl groups are on same side.
(b)
Interpretation:
The structure of trans-3-heptene should be drawn.
