Question

Dispersion forces are due to ___ a. permanent dipoles. b. temporary dipoles. c. hydrogen bonding. d. ionic interactions. e. protons. Which type of intermolecular interaction exists for all compounds? a. ion-ion b. dipole-dipole c. dispersion d. hydrogen bonding e. dipole-induced dipole Polarizability refers to ___ a. the ease with which the electron cloud of an atom or molecule can be distorted. b. the magnitude of the dipole moment of a molecule. c. the ease with which a hydrogen bond can form. d. the perturbation in electron density because of hydrogen bonding. e. the ability to transmit polarized light. Which of the following would you predict has the highest polarizability? a. CO_2 b. CBr_4 c. Cl_2 d. CH_4 e. CCl_4

Explanation / Answer

33. The right answer is option b. Temporary dipoles.

Dispersion forces represent the weakest intermolecular force. It is a temporary attractive force that arises when electrons of two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force is sometimes referred as induced dipole-induced dipole attraction. Hence this is the correct answer.
