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.

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.

I have a question about this problem involving mechanisms and drawing curved arrows for acids and bases. I know we need to identify the nucleophile and electrophile, but are there different types of reactions? For instance, what about Grignard reagents and other types that I might not be familiar with? Can you help me with this? I want to identify the names of the mechanisms for problems 1-14, such as Gilman reagents and others. Are they all the same? Also, could you rewrite it so I can better understand? The handwriting is pretty cluttered. Additionally, I need to label the nucleophile and electrophile, but my main concern is whether those reactions differ, like the "Brønsted-Lowry acid-base mechanism, Lewis acid-base mechanism, acid-catalyzed mechanisms, acid-catalyzed reactions, base-catalyzed reactions, nucleophilic substitution mechanisms (SN1 and SN2), elimination reactions (E1 and E2), organometallic mechanisms, and so forth."
