Concept explainers
(a)
Interpretation:
Skeletal structures of molecule A should be drawn by showing the stereochemistry at the carbon-carbon double bond.
Concept Introduction:
The skeletal structure of a molecule is the formulaic representation excluding hydrogens.
(b)
Interpretation:
Stereoisomer of structure A should be drawn.
Concept Introduction:
Alkenes are hydrocarbon molecules that consist of a carbon-carbon double bond which has the general formula of
Isomers are the different molecules that have the same molecular formula but differ in molecular arrangement in the space. There are several groups of isomers.
Stereoisomers are the form of isomers which have different three-dimensional orientations in the space.
(c)
Interpretation:
Constitutional isomer of structure A should be drawn.
Concept Introduction:
Alkenes are hydrocarbon molecules that consist of a carbon-carbon double bond which has the general formula of
