Concept explainers
(a)
Interpretation:
It is to be identified which two hydrogen atoms in butanal (
Concept introduction:
Constitutional isomers are the isomers having the same molecular formula but different connectivity. For the given structure, replacing hydrogen atoms by halogen atoms attached to different carbon atoms would generate constitutional isomers.
(b)
Interpretation:
It is to be identified which two hydrogen atoms in butanal (
Concept introduction:
Configurational isomers are the stereoisomers which have the same connectivity of atoms and which can’t be interconverted by rotations around single bonds. Enantiomers are the type of constitutional isomers, which are non-superimposable mirror images of each other. For the given structure, replacing the hydrogen atoms on the wedge and dash bond by halogen atoms attached to the same carbon atoms would generate enantiomers.
(c)
Interpretation:
It is to be identified which two hydrogen atoms in butanal (
Concept introduction:
Conformers are the stereoisomers which have the same connectivity of atoms but which can be interconverted by rotations around single bonds only. For the given structure, replacing hydrogen atoms on the carbon atom having more than two identical groups or atoms will yield conformational isomers.

- There are 17 possible alkene isomers with the formula C6H12. Draw structures of the five isomers in which the longest chain has six carbon atoms, and give the name of each. Are any of these isomers chiral? (There are also eight isomers in which the longest chain has five carbon atoms, and four isomers in which the longest chain has four carbon atoms. How many can you find?)arrow_forwardAre there alkene isomers with the molecular formula C2H3Cl?arrow_forward1. a. Draw and name the five cycloalkane structures of formula C5H10. Can any of these structures give rise to geometric (cis-trans) isomerism? If so, show the cis and trans stereoisomers. b. Draw and name the eight cycloalkane structures of formula C6H12 that do not show geometric isomerism. c. Draw and name the four cycloalkanes of formula C6H12 that do have cis-trans isomers. 2. Each of the following descriptions applies to more than one alkane. In each case, draw and name two structures that match the description. (a) an isopropylheptane (b) a diethyldecane (c) a cis-diethylcyclohexane (d) a trans-dihalocyclopentane (e) a (2,3-dimethylpentyl)cycloalkane (f) a bicyclononane 3. 2. refer to the photo attached and answer the ff.3-33, 3-34arrow_forward
