Which one of the following statements is INCORRECT:
(A)
X-ray crystallography can give the three-dimensional arrangement of all the atoms in a molecule
The ratio of the two main isotopes of Cl (chlorine) is about 3:1
(B)
(C)
The index of hydrogen deficiency (IDH) for C5H8O is 4.
(D)
Generally speaking, the longer the wavelength of the UV-Vis spectrum maximum (2max), the more
conjugated the molecule is.
The energy of photons used in UV-Vis spectroscopy is much higher than those used in NMR
spectroscopy.
(E)
