Which of the following would you expect to be more soluble in water than in benzene? (Select all that apply.)
(a)
(b)
(e)
Interpretation:
The compounds that is more soluble in water than benzene is/are to be identified.
Concept introduction:
The various kinds of interactions that bind a molecule are known as intermolecular forces. These can be dispersion, dipole–dipole, ion–dipole,and hydrogen bonding.
The solubility of a compound depends on the intermolecular forces present. Apolar solvent is soluble in apolar solvent only. A compound is soluble in water only when it is able to form hydrogen bonds with it.
Answer to Problem 1KSP
Solution: The correct answersareoption (a) and option (e).
Explanation of Solution
Reason for the correct option:
The molecule, methanol
Thus, it is soluble in water more readily. On the other hand, benzene is a nonpolar molecule. So, methanol is insoluble in benzene.
Potassium iodide
Hence, option (a) and option (e) are correct.
Reasons for the incorrect options:
Option (b) is incorrect because
Option (c) is incorrect because trans-dichloroethene is a nonpolar molecule. It is insoluble in water. So, this option is incorrect.
Option (d) is incorrect because cis-dichloroethene is a polar molecule but it is unable to form hydrogen bonds in water. It is, therefore, insoluble in water. So, this option is incorrect.
Hence, options(c) and (d) are incorrect.
