Pleae help with these homework questions. **Use the References to access important values if needed for this question.****a.** Use strain energy increments in the OWL Table Reference (see References button, Strain Energy Increments) to calculate the energy difference between the two chair conformations of the compound below.**b.** Specify substituent positions (axial or equatorial) in the more stable chair.**c.** Estimate the percent of the more stable chair at equilibrium at 25°C.*(To determine the percent of the more stable chair at equilibrium, first calculate \(K_{eq}\) and then use this value to find the percentage.)*[Image: A cyclohexane ring with a methyl group and an isopropyl group attached. The methyl group is on the second carbon, and the isopropyl group is on the fourth carbon.]**Answers:**- **a.** The energy difference is \(1.9 \, \text{kJ/mol}\).- **b.** In the more stable chair: - The **methyl** group is in the **equatorial** position. - The **isopropyl** group is in the **equatorial** position.- **c.** At 25°C, the equilibrium percent of the more stable chair conformation is approximately **>95%**.[Answer submission options: "Submit Answer," "Retry Entire Group" with a note of "9 more group attempts remaining."] **Exercise: Naming Organic Compounds****Objective:** Write an acceptable IUPAC name for the compound below. Include 'cis' and 'trans' as part of the name when stereochemistry is illustrated.**Compound Image Description:** - The compound is a cyclohexane derivative.- It includes a bromine (Br) atom attached to the cyclohexane ring.- There is a methyl group (CH₃) also attached to the ring.- The bromine is shown with a wedge (indicating it is above the plane) and the methyl group is shown with a dash (indicating it is below the plane).**Input Field:** "The IUPAC name is" [Text box for user input]**Buttons:**- "Submit Answer"- "Retry Entire Group"- "7 more group attempts remaining"**Instruction:** Fill in the IUPAC name considering the given stereochemistry and submit your answer. You have multiple attempts to refine your response.

if needed for questie a. Use strain energy increments in the OWL Table Reference (see References button, Strain Energy Increments) to calculate the energy difference between the two chair conformations of the compound below. b. Specify substituent positions (axial or equatorial) in the more stable chair. c. Estimate the percent of the more stable chair at equilibrium at 25°C. (To determine the percent of the more stable chair at equilibrium, first calculate Kea, and then use this value to find the percentage.) CH3 CH3 H3C
