Concept explainers
(a)
To determine: The compound that has zero dipole moment and higher boiling point.
Interpretation: The compound that has zero dipole moment and higher boiling point is to be identified.
Concept introduction: The dipole moment gives the polarity of the compound due to polarity difference of the atoms of the compound. It gives the charge separation of the molecule.
Larger the difference in the electronegativies of the atoms, larger is the dipole moment of the molecule. The compound that has high dipole moments has high boiling point due to presence of dipole-dipole attraction.
(b)
To determine: The compound that has zero dipole moment and higher boiling point.
Interpretation: The compound that has zero dipole moment and higher boiling point is to be identified.
Concept introduction: The dipole moment gives the polarity of the compound due to polarity difference of the atoms of the compound. It gives the charge separation of the molecule.
Larger the difference in the electronegativies of the atoms, larger is the dipole moment of the molecule. The compound that has high dipole moments has high boiling point due to presence of dipole-dipole attraction.
(c)
To determine: The stability of the given compounds and the amount of energy that makes one of them stable.
Interpretation: The stability of the given compound is to be determined and the amount of energy that makes one of them stable is to be calculated.
Concept introduction: The stability of
Heat of hydrogenation of an alkene is the standard enthalpy for the catalytic hydrogenation of the alkene. The value of heat of hydrogenation is always negative.

- True or False 1. Liebermann-Burchard Test -Color change is due to increasing conjugation of the double bond in adjacent fused ring 2. Liebermann-Burchard Test -Acetic anhydride reacts with the aliphatic hydrocarbon. 3. Salkowski Test - The chloroform layer turns red. 4. Salkowski Test - Involves the reagents chloroform, sulfuric acid and acetic anhydride 5. Liebermann-Burchard Test -Reaction involved is esterification. 6. Keller-Killiani Test - Involves color reaction of the sugar 2-deoxyhexose 7. Salkowski Test - The upper layer turns yellow with green fluorescence 8. Liebermann-Burchard Test -Must observe the color right away because it happens in a very short period of time. 9. Liebermann-Burchard Test - Chloroform was added to react with sulfuric acid. 10.
