Why are lithium halides somewhat covalent compared to other alkali metal halides?

Options

  1. ABecause lithium is a noble gas
  2. BBecause lithium has a high atomic number
  3. CDue to the high polarization capability of the lithium ion
  4. DBecause lithium has a large atomic radius

Correct answer

C. Due to the high polarization capability of the lithium ion

Step-by-step solution

Lithium halides are somewhat covalent because the small size of the Li+ ion allows it to distort the electron cloud around the larger halide anion, leading to covalent character in the bonding.
