Why do many fluorides tend to be less soluble than the corresponding chlorides?

Options

  1. AFluorides have a lower lattice enthalpy than chlorides.
  2. BChlorides have a lower lattice enthalpy than fluorides.
  3. CFluorides have a higher lattice enthalpy than chlorides.
  4. DChlorides have a higher lattice enthalpy than fluorides.

Correct answer

C. Fluorides have a higher lattice enthalpy than chlorides.

Step-by-step solution

Many fluorides tend to be less soluble than the corresponding chlorides because fluorides generally have a higher lattice enthalpy, making it more difficult for them to dissolve.
