question 71

Multiple Choice

Which of the following statements regarding acid and base ionization in water is NOT correct?

• A)A hydrogen atom directly bonded to an oxygen atom in a molecule is always significantly more acidic than water.
• B)In strong acids, the acidic protons are generally bonded to highly electronegative elements such as O, Cl, Br, or I.
• C)When a hydrogen atom is released as an H⁺ ion from an electronegative atom in an acid, the bonding pair of electrons remains on the electronegative atom.
• D)Ionization of a strong acid in water is assisted by the strong dipole-dipole interactions between its ionizable H atoms and the O atoms in water molecules.
• E)Ionization of water to form hydroxide in the presence of a base is often assisted by strong dipole-dipole interactions between H atoms in water and a lone pair of electrons in the base.
