Concept explainers
(a)
Interpretation: The compound having the higher boiling point has to be identified.
Concept Introduction:
Boiling point: It is the temperature at which liquid converts to vapor. At boiling point the vapor pressure of liquid and the pressure of the surroundings are equal.
The boiling point of a liquid increases as the intermolecular forces within the compound increases.
(b)
Interpretation: The compound having the higher boiling point has to be identified.

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.
