The reaction affords three different products (all C8H15Cl). In this reaction, the rates of hydrogen abstraction of primary : secondary : tertiary are 1 : 3.5 : 5.
Predict the percent areas of all of the products ofmonochlorination of 1,4-dimethylcyclohexane.
rank cis-1,2-dimethylcyclohexane, cis-1,3-dimethylcyclohexane and cis-1,4-dimethylcyclohexane in increasing order of stability.
Draw the Newman structures for 1,2 dimethycyclohexane , 1,3 dimethylcyclohexane and 1,4 dimethylcyclohexane. Please draw the cis and trans for each. thank you
Cis-1,2-dimethylcyclohexane and cis-1,4-dimethylcyclohexane have very similar heats of combustion. However, cis-1,2-dimethylcyclohexane is slightly higher. Why?
explain why the two stereoisomers of 1,4-dimethylcyclohexane are achiral
Draw the newman projections for 1,4 dimethylcyclohexane for cis and trans with ring flip. there should be 4 newman projections.

Draw 1,4 -Dimethylcyclohexane in hawthorne projection first, then show it in chair conformation in cis then show it flipped. Also, then show it in chair conformation in trans and then show it flipped.
Which, if either, of the 1,4-dimethylcyclohexane isomers shown below is more stable? Explain your answerusing depictions of the relevant conformational equilibria.
Following are the alternative chair conformations for trans-1,4-dimethylcyclohexane: . Using the data for ΔG for monosubstituted cyclohexanes at room temperature (25ºC) and the representative value* for the gauche interaction of two equatorially positioned substituents in the 1,2-position: a) Calculate the difference in the Gibbs free energy between the second and first conformation including the algebraic sign. kJ/mol b) Given your value in (a), calculate the percent of the chair, indicated as B, presented in an equilibrium mixture of the conformers...
