Concept explainers
(a)
Interpretation:
Structures of A and B should be identified as constitutional isomers, stereo isomers or not isomers of each other.
Concept Introduction:
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.
Constitutional isomers are the form of isomers which have atoms bonded to each other in different ways.
(b)
Interpretation:
Structures of A and C should be identified as constitutional isomers, stereo isomers or not isomers of each other.
Concept Introduction:
Alkenes are hydrocarbon molecules that consist of a carbon-carbon double bond which has the general formula of

- 5) Based on the structures of lycopene and ẞ-carotene, which are two chemicals found in another common vegetable, the tomato, answer the following questions: a) Are they stereoisomers, constitutional isomers or not even isomers? b) Do you expect them to be relatively polar or nonpolar substances? Why? c) How many double bonds are in lycopene? How many in ẞ-carotene? d) As lycopene is transformed into ẞ -carotene, how many pi electrons from the double bonds are transformed into single bonds? How many new single bonds are being formed in ẞ-carotene? e) The first step of a possible mechanism for the ring closure in the transformation is outlined below (only part of the structure is shown for simplicity).
