Homework Answers
3. mirror image of model E is uploaded as image file.
4. carbon no-1 and 3 both are sterecenters. so two chiral center is present.
5. the model E is chiral having point group C1.
6. It is not a meso compound.
7. No it is not identical to its mirror image. they are enantiomers.
8. No, plane of symmetry is there.
9. Plane of symmetry is absent.
10. yes model is E optically active and after flipping it does not produce mirror image enantiomers.

1. Construct a model consisting of a tetrahedral carbon center with four different component atoms attached: red, white, blue, green; each color represents a different group or atom attached to carbon. Does this model have a plane of symmetry (1a)? A plane of symmetry can be described as a cutting plane-a plane that when passed through a model or object divides it into two equivalent halves; the elements on one side of the plane are the exact reflection of the...

3. Diastereomers and Meso Forms. When a molecule has two or more stereogenic centers, stereoisomers that are not mirror images can exist; these are called diastereoisomers. Within this general class, there are special types of stereoisomers that are always optically inactive and are called meso forms. Construct a model with four different colored balls about a carbon center. Construct another identical to the first and verify this by the superimposition test. Now remove the same colored balls, blue (C from...

e. Of course, cyclohexanol never exists in a flat hexagonal form. It is just drawn this way for convenience. It exists in one of two chair conformations that are rapidly interconverting at room temperature, the conformation with the hydroxyl in the equatorial position being favored. Гон — Ян Make a model of cyclohexanol with the OH in the equatorial position. Now do a chair flip, so that the OH is in the axial position. Can you find a plane of...
