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-cyclohexanol.
(B) b
(C) c
(D) d
HO 2 2 OH cis-4-tert-Butylcyclohexanol trans-4-tert-Butylcyclohexanol A) In the cis-isomer the coupling constant (J) between the proton at C1 and the axial B) In the cis-isomer the coupling constant (J) between the proton at C1 and the C) In the trans-isomer isomer the coupling (J) constant between the proton at C1 and D) In the trans-isomer the coupling constant (J) between the proton at C and the protons at C2 and C6 is 8 Hz. equatorial protons at C2 and C6 is 2 Hz. the axial protons at C2 and C is 8 Hz. equatorial protons at C2 and C6 is 2 Hz.Explanation / Answer
The statement (A) a is incorrect.
In the cis isomer, the coupling constant (J) between the proton at C1 and the axial protons at C2 and C6 will be less than 8 Hz as the distance between protons is large,
