65. Which of the following statements about I D NMR and 2D NMR spectroscopy is INCORRECT?
(A) ID NMR is faster than 2D NMR.
(B) ID NMR gives less information than 2D NMR.
(C) 2D NMR spectrum provides information about the spatial relationships between different nuclei in the sample, such as the distances and angles between atoms.
(D) 2D NMR distinguishes between the overlapping signals that exist in larger molecules.
(E) The advantage of 2D NMR spectroscopy is that it requires only one frequency axis.
