Question

Consider the structures and read each statement carefully (see attached image). Choose the letter that represents the statement that incorrectly describes the expected coupling of the proton at C1 in the cis and trans relative stereoisomers of
4-tert-butylcyclohexanol.

HTI HO OH TY Cis-4-tert-Butylcyclohexanol trans-4-tert-Butylcyclohexanol A) In the cis-isomer the coupling constant (J) between the proton at C and the axial protons at C2 and Cf is 8 Hz. B) In the cis-isomer the coupling constant (J) between the proton at C and the equatorial protons at C2 and C6 is 2 Hz. C) In the trans-isomer isomer the coupling (J) constant between the proton at C, and the axial protons at Cz and C5 is 8 Hz D) In the trans-isomer the coupling constant (J) between the proton at C, and the equatorial protons at C2 and Cf is 2 Hz.
