The Haworth projections of cis and trans-1-4-dimethylcyclohexane are drawn and its stability should be comparatively explained. Concept Introduction: Haworth projection: The representation of cyclic chemical compounds by normal ring structure and the substituents can either pointing up or down on this ring is called Haworth projection . Conformational isomers: The two or more compounds have same molecular formula and different structural formulas from the result of C-C single bond rotations are called conformational isomers. The atom or group is occupy at similar to a vertical axis passing through the chair conformation of Cyclohexane ring is called axial position. The atom or group is occupy at similar to horizontal axis passing through the chair conformation of ring is called equatorial position . The substituents are occupy in equatorial position is more stable than axial because of the 1,3-diaxial interactions are less in equatorial position.

Interpretation:

The Haworth projections of cis and trans-1-4-dimethylcyclohexane are drawn and its stability should be comparatively explained.

Concept Introduction:

Haworth projection:

The representation of cyclic chemical compounds by normal ring structure and the substituents can either pointing up or down on this ring is called Haworth projection.

Conformational isomers:

The two or more compounds have same molecular formula and different structural formulas from the result of C-C single bond rotations are called conformational isomers.

The atom or group is occupy at similar to a vertical axis passing through the chair conformation of Cyclohexane ring is called axial position.

The atom or group is occupy at similar to horizontal axis passing through the chair conformation of ring is called equatorial position.

The substituents are occupy in equatorial position is more stable than axial because of the 1,3-diaxial interactions are less in equatorial position.

A student proposes the transformation below in one step of an organic synthesis. There may be one or more reactants missing from the left-hand side, but there are no products missing from the right-hand side. There may also be catalysts, small inorganic reagents, and other important reaction conditions missing from the arrow. • Is the student's transformation possible? If not, check the box under the drawing area. • If the student's transformation is possible, then complete the reaction by adding any missing reactants to the left-hand side, and adding required catalysts, inorganic reagents, or other important reaction conditions above and below the arrow. • You do not need to balance the reaction, but be sure every important organic reactant or product is shown. + T G OH де OH This transformation can't be done in one step.
