Which of the following isomer (A – D) will show the following 1H-NMR spectrum? Explain your answer by assigning the different peaks and their splitting patterns (A zoom-in on the peak centered around 1.8 ppm is also shown for better clarity of the splitting pattern). H3C(A) CH 3H3CH3COH H3COHOH(B)OHCH CH3
