Who was able to determine the distance b/w "K+"and "Cl-" in potassium chloride crystal?

Correct answer: B. Pauling.

  • A. Bohr's.
  • B. Pauling.
  • C. Berzelius.
  • D. Rutherford.

Explanation

Linus Pauling used X-ray crystallography to determine the atomic structure of various molecules and crystals. In the case of potassium chloride, he directed X-rays at a crystal of the compound, which caused the X-rays to diffract off the atoms in the crystal. By analyzing the diffraction pattern, Pauling was able to determine the positions of the potassium and chloride ions in the crystal lattice, as well as the distance between them. This technique allowed him to make important contributions to our understanding of the structure and properties of various materials.

About Chemical Bonding

Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
