Concept explainers
Interpretation:
The structural formulas for given compounds are to be written.
Concept introduction:
In the system of
The longest continuous carbon chain is selected.
The chain is numbered in such a manner, that the carbon bearing the
The parent alcohol ends with –ol.
The position of the alcoholic group is indicated by writing the number.
The names and positions of each substituent are determined.
The number of identical groups is indicated by di, tri, tetra, and so on.
The position number and the names of substituents are placed in alphabetical order before the root name.
If the higher priority groups are placed on the same side of a double bond, then the configuration is Z. On the other hand, if these are on the opposite sides, then it is E.
Stereocenters having the substituents arranged in clockwise manner in order of priority are indicated by the R system of nomenclature, whereas if it is anti-clockwise, then the nomenclature used is the S system.
