Interpretation: The information regarding the stability of
Concept introduction: Cis-trans isomerism determines the position of position of different groups relative to each other. If the different groups points in the same direction then they are said to be cis with respect to each other but if they point in the opposite direction then they are trans with respect to each other.

- The NMR spectrum of bromocyclohexane indicates a low field signal (1H) at δ 4.16. To room temperature, this signal is a singlet, but at -75 ° C it separates into two peaks of unequal area (but totaling one proton): δ 3.97 and δ 4.64, in ratio 4.6: 1.0. How do you explain the doubling in two peaks? According to the generalization of the previous problem, what conformation of the molecule predominates (at -75 ° C)? What percentage of the molecules does it correspond to?
