(a) Interpretation: The two possible chair conformations for the cyclohexanol should be drawn and named every substituent as axial or equatorial and most stable conformer should be selected. Concept introduction: when the cyclohexanering converts from one chair conformation to another, the equatorial hydrogen atoms areconverted into axial hydrogen atoms and vice versa. When the cyclohexane has one substituent then the conformation which contain the substituent in equatorial position is more stable due to less steric strain with axial hydrogen atoms.

Interpretation Introduction

(b)

Interpretation:

The two possible chair conformations for the trans-3-methylcyclohexanol should be drawn and named every substituent as axial or equatorial and most stable conformer should be selected.

Concept introduction:

when the cyclohexane ring converts from one chair conformation to another, the equatorial hydrogen atoms are converted into axial hydrogen atoms and vice versa.

When the cyclohexane has one substituent then the conformation which contain the substituent in equatorial position is more stable due to less steric strain with axial hydrogen atoms.

When two substituents are present in the structure, in order to find the more stable conformation can be determined by looking at the groups in the axial position.

When a bulkier group present in the axial position, that conformation get less stable.

Place the methyl groups by drawing the axial and equatorial positions on the cyclohexane structure in the chair conformations next to the cyclohexane derivatives named below.

Hello, I was reading an answer from the book Organic Chemistry by Brown et al. The question is 2.51 "Draw alternative chair conformations for each substituted cyclohexane and state which chair is more stable." There are then 4 cyclohexanes (labeled a-d). For the "a" cyclohexane, the substituents are arranged as a combination of axial and equatorial in both chair conformations. However, for the "b," "c," and "d," cyclohexanes one chair has only equatorial substituents, and the other chair has only axial substituents. Why is the "a" chair conformation different? https://www.bartleby.com/solution-answer/chapter-2-problem-251p-organic-chemistry-8th-edition/9781305580350/draw-alternative-chair-conformations-for-each-substituted-cyclohexane-and-state-which-chair-is-more/4532cd91-c341-11e9-8385-02ee952b546e
