Concept explainers
Write structural formulas for each of the following:
Interpretation:
The structural formula of the given compounds is to be written.
Concept introduction:
When writing the structural formula of any compound, first the functional group from the suffix of the given name is identified.
The longest carbon chain containing the functional group is located.
The carbon atoms of the chain are numbered in a way that the functional group is at lowest numbered carbon atom.
Substituents are attached to the parent chain according to their positions given in the name.
In alkenes, the Z isomers have the higher ranked substituents on the same side of the double bond, and in E isomers, higher ranked substituents are on the opposite sides of the double bond.
