Concept introduction:
A monosubstituted cyclohexane is more stable when the bulkier substituent occupies an equatorial position. The equatorial conformer is more stable than the axial conformer because there is more room for the substituent in the equatorial position. In the axial position, the substituent gets significant steric strain due to repulsion between the electrons on the axial substituents and those on the axial H atoms two positions away on the ring. This is called

- Measure the C-C-C and C-C-H bond angles in the energy-minimized models of cis and trans isomers of cyclooctene. Compare these values with those predicted by VSEPR. In which isomer are deviations from VSEPR predictions greater?arrow_forwardIs the geometry of CH2BrCl, the same as CH3Cl and CH4? Briefly explain the evidence for your answerarrow_forwardwhich of the molecules is flat? a) C6H6 b) C6H12 (cyclohexane) c) CH4 d) CH2 = CH2 e) a and darrow_forward
- Consider the following representation of 1,2-dimethylcyclohexane.Which of the following describes the molecule represented? What is the molecular formula (in the order CH) of the compound?arrow_forwardCyclopropane and cyclobutane have similar strain energy despite the fact that the C—C—C bond angles of cyclopropane are much smaller than those of cyclobutane. Suggest an explanation for this observation, considering all sources of strainarrow_forwardThe carbon–carbon bond length in C2H2 is 1.20 Å, that in C2H4 is 1.34 Å, and that in C2H6 is 1.53 Å. Near which of these values would you predict the bond length of C2 to lie? Is the experimentally observed value, 1.31 Å, consistent with your prediction?arrow_forward
- Cyclopropane and cyclobutane have similar strain energy despite the fact that the C—C—C bond angles of cyclopropane are much smaller than those of cyclobutane. Suggest an explanation for this observation, considering all sources of strain discussed in Chapter 4.arrow_forwardC2H6 Draw the structures of the two isomers, known as dimethyl ether and ethanol, of this molecular formula. Label them correctly.arrow_forwardMolecules that have the same molecular formula, but different atomic connections are called constitutional isomers. Draw and name the five constitutional isomers of C6H14. Is this correct answer from this paper that I draw for the name the five constitutional isomers of C6H14? Can you explain to me that why is the different atomic connections are called constitutional isomers?arrow_forward
- In the molecule 2 methyl hexane, how many of the C-C bonds have staggered conformers that are equally stable? The answer is 3 but I don't understand how they got there.arrow_forwardIn the cis and trans molecular models of 1,2-dichlorocyclobutane Is isomerization of both compounds possible at room temperature? Isomerization means the conversion of the cis compound to the trans (or vice versa) by rotation of the bonds. Explain whyarrow_forwardConsider 1,2-dimethylcyclohexane.Q: Which isomer, cis or trans, is more stable and why?arrow_forward
