Concept explainers
(a)
To determine: The reason corresponding to fact that given compound II has almost triple the molecular weight of compound I, but has a lower boiling point.
Interpretation: The reason corresponding to fact that given compound II has almost triple the molecular weight of compound I, but has a lower boiling point is to be explained.
Concept introduction: The boiling point of a liquid is defined as the temperature at which molecule in liquid phase has a vapour pressure equals to atmospheric pressure surrounding the liquid.
Hydrogen bonding is one of the major factors to that affect in the determination of the higher or lower boiling point of the compounds.
(b)
To determine: The reason corresponding to fact that dipole moment of compound II is much lower than a dipole moment of compound II being the presence of the six electronegative fluorine atoms.
Interpretation: The reason corresponding to fact that dipole moment of compound II is much lower than a dipole moment of compound II being the presence of the six electronegative fluorine atoms is to be explained.
Concept introduction: Dipole moment is defined as measure to check the polarity of the compounds. In polar molecules there is a large dipole moment is present.
Polar molecules like
(c)
To determine: The reason corresponding to fact that compound II is stronger acid than compound I.
Interpretation: The reason corresponding to fact that compound II is stronger acid than compound I is to be stated.
Concept introduction: The acidity of the compounds is determined on the basis of

- Why do you wash the dichloromethane solution of your reductive amination product with sodium bicarbonate, rather than dilute aqueous HCl? a) Sodium bicarbonate is a good method of removing aldehydes from organic solvent.b) The amine product will be protonated by acid and remain in the aqueous layer as a salt.c) Sodium bicarbonate transfers the amine starting material into the aqueous layer.d) Sodium bicarbonate reacts with leftover NaBH(OAc)3 and removes it from the mixture.arrow_forwardNeed help with these two.
