Write TRUE if the BOLD word/phrase makes the statement correct. Otherwise, write the correct WORD/PHRASE that will make the statement true. If there are two bold words/phrases in a number, write your answer for EACH of the bold words/phrases. 1. The anti-staggered conformation of butane, in which the methyl groups have a dihedral angle of less than 180°, has the highest energy. 2. The formation of 2-methylpropene as side product in the synthesis of tert-butyl chloride is a nucleophilic substitution reaction. 3. The generation of tertiary carbocation is the rate-determining step in tert-butyl chloride synthesis.
Between the cis and trans configuration of 1-chloro-4-methylcyclohexane, which is the most stable stereoisomer and configuration? To prove your argument, draw a model or use a modeling software to model cis- and trans-1-chloro-4-methylcyclohexane (show all the hydrogens and ensure proper chair conformation) and use arrows to show where steric strain occurs.
Given that the free energy of the twist-boat conformer of cyclohexane is 5.3 kcal/mol greater than that of the chair conformer, calculate the percentage of twist-boat conformers present in a sample of cyclohexane at 25 °C. Does your answer agree with the statement made in Section 3.13 about the relative number of molecules in these two conformations?

Following is a planar hexagon representation of L-fucose, a sugar component of the determinants of the A, B, O blood group typing. For more on this system of blood typing, see Chemical Connections: A, B, AB, and O Blood Group Substances in Chapter 25. (a) Draw the alternative chair conformations of L-fucose.

Gibbs free energy differences between axial-substituted and equatorial-substituted chair conformations of cyclohexane were given in Table 2.4. (a) Calculate the ratio of equatorial to axial tert-butylcyclohexane at 25C. (b) Explain why the conformational equilibria for methyl, ethyl, and isopropyl substituents are comparable but the conformational equilibrium for tert-butylcyclohexane lies considerably farther toward the equatorial conformation.
Cyclohexane derivatives exist primarily in the most stable of the available chair conformations. Give the position, axial or equatorial, of each of the three groups shown when the ring is in the most stable chair conformation. If a group divides its time equally between axial and equatorial positions, indicate this with ax/eq.
Why is the percentage of molecules with the substituent in an equatorial position greater for isopropylcyclohexane than for fluorocyclohexane?
Between the cis and trans configuration of 1-chloro-3-methylcyclohexane, which is the most stable stereoisomer and configuration? To prove your argument, use your models or a modelling software to model cis- and trans-1-chloro-3-methylcyclohexane (show all the hydrogens and ensure proper chair conformation) and use arrows to show where steric strain occurs. Include these photos in your answer.
The highest energy conformation of ethane has 12 kJ/mol of strain. The two highest conformations of butane have 16 and 19 kJ/mol of strain, respectively. How much strain does the highest energy conformation of 2,3-dimethylbutane have?
Stereoisomers share the same connectivity and differ only in the way their atoms are arranged in space. Draw the structure of a compound that is a stereoisomer of trans-1,2-dibromocyclobutane.(Note that the question asks for a different stereoisomer of the named compound and not the named compound itself.)Use the wedge/hash bond tools to indicate stereochemistry where it exists.In cases where there is more than one answer, just draw one.
