Question

Arrangement of atoms in Molecular Solids can be studied with the help of? 

Options
  • A

    Gamma Rays  

  • B

    X-Rays

  • C

    Spectrometry

  • D

    Electron Microscope  

Explanation

X-ray crystallography is a method of determining the 3d arrangement of atoms within a molecule. Hence the arrangements of atoms in the solids can be determined using x rays.

Gamma rays are not commonly used to study the arrangement of atoms in Molecular solids.

X-ray crystallography is a method of determining the 3d arrangement of atoms within a molecule. Hence, the arrangement of atoms in the solids can be determined using X-rays.

Spectrometry is also not commonly used to study the arrangement of atoms in molecular solids

The arrangement of atoms in molecular solids cannot be studied with the help of an electron microscope because the wavelength of Electrons is much shorter than the interatomic distances in Molecular solids.
