Consider the following four solutions:
- NaCl in water
- Acetic acid in water
- Acetic acid in benzene
- Naphthalene in benzene
Which of these solutions has the strongest solute-solvent interactions and the interaction is of which type?
Select one:
a. Acetic acid in water; hydrogen bonding
b. Acetic acid in benzene; dipole-induced dipole interaction
c. NaCl in water; ion-dipole interaction
d. Naphthalene in benzene; London Dispersion Forces
e. NaCl in water; hydrogen bonding
Homework Answers
Answer is c)NaCl in water ;ion dipole interaction.
Intermolecular forces in decreasing order: ion-ion>ion-dipole>hydrogen bonds (only when H is bonded to O,N,F)>dipole-dipole >dipole-induced dipole>dispersion forces .
From the options above ion dipole interaction in NaCl-water is the strongest.
So answer is option c.
Thank you.
