Question

Question 3 [1.3 pts] Based on the information provided in Figure #1 what strain energy (in kcal/mole) is associated with a single R:R gauche interaction (where R represents the same unspecified alkyl group)? Carry maximum number of digits to final answer then enter just the numerical value rounded to one decimal place. Don't be alarmed when Canvas adds trailing zeros to the number you type in. This action will not affect the grading of your answer. Figure 1 CH2CH, H Total strain energy is 8.6 kcal/mole

Explanation / Answer

Total strain is 8.6 kcal/mole.

one ethyl and H 1,3 diaxial interaction strain is equla to 1.74 kcal / moles. Two ethyl and H 1,3 diaxial interaction strainie is equal to 3.48 kcal / mole.

Gauche strain = 8.6-3.5= 5.1 kcal/mole.
