Concept explainers
(a)
Interpretation:
The compounds showing cis-trans isomerism for the given compounds has to be determined.
Concept introduction:
Cis-trans terminology is used for two non-similar groups attached
If the two identical groups are attached on each side of double bond in same side, then it is cis alkenes.
If the two identical groups are attached on each side of double bond in opposite manner, then it is trans alkenes.
(b)
Interpretation:
The isomers shown in part (a) has to be drawn and labeled.
Concept introduction:
Cis-trans terminology is used for two non-similar groups attached alkenes.
If the two identical groups are attached on each side of double bond in same side, then it is cis alkenes.
If the two identical groups are attached on each side of double bond in opposite manner, then it is trans alkenes.

- 13. When a chain of carbons has all single C-C covalent bonds with a single C=C double bond such that the C backbone looks like this R1-C-C=C-C-R2 this molecule has two very different shapes. These 2 alternate shapes are called: a) geometric isomers b) structural isomers c) stereo isomers d) none are correctarrow_forwardConstitutional isomers are compounds which have the same molecular formula but different structural formulae. They are different compounds with different physical and chemical properties.a. Rearrange your model of n-hexane to make as many possible isomers of C6H14 as you can. Draw the structural formula and write down the IUPAC name for each isomer that you make.b. Constitutional isomers can also have different functional groups. Make all possible isomers of C3H8O. Write down the structural formulae and IUPAC names for all the compounds you make. Hint: Consider alcohol and ether functional groups.arrow_forwardWhat are conformational isomers?arrow_forward

Alkane with molecular formula C6H14 2. ● ● . ● Cis isomer (Line structure) ● IUPAC name of cis isomer ● Trans isomer (Line structure) IUPAC name of trans isomer Isomer 1 (Line structure) IUPAC name of Isomer 1 Isomer 2 (Line structure) IUPAC name of Isomer 2 .arrow_forwardPlease answer both questionsarrow_forwardA. Structural Isomerism of Alkanes Construct models for the five alkanes that have the molecular formula C6H14. All five of your models should have the same number of each type of atom, but they should have the atoms connected in a different order. Thus the molecules they represent are structural isomers of one another. Note the tetrahedral geometry of each carbon atom. Draw an extended and a condensed structure (NOT skeletal/line angle) of each structural isomer, then determine its IUPAC name. Recall that since the IUPAC name specifies the number of each type of atom and how they are connected, each structural isomer will have a different name. Each name should very specifically describe the structure.
