Answer:

  • The NaCl has more attraction as compare to KCl.

Step-by-step explanation:

  • As we know down the group size is increases.
  • As the size of K is greater than Sodium.
  • Due to greater size of atom, the distance between the K and Cl is greater than NaCl .
  • Due to greater distance between the atoms , attraction become less.

Summary:

  • Greater size (greater radius) between atoms , lesser will be attraction.
