Concept explainers
(a)
Interpretation:
The skeletal structure of E-3,4-dimethyl-3-heptene needs to be drawn and the reason for naming trans in spite of having identical groups needs to be explained.
Concept Introduction :
The compounds are named as E-Z based on analysis of the groups at the end of double bond. The naming is done as per the CIP rules wherein the highest priority gets its preference meaning the highest
(b)
Interpretation:
The configurational isomers of E-3,4-dimethyl-3-heptene needs to be drawn and named.
Concept Introduction :
Configurational isomers are stereoisomers which cannot get converted to another compound by rotation of molecules about a single bond. It is possible to be converted only by breaking of the bonds.
