All of the following share the same crystal structure except.

All of the following share the same crystal structure except.

Options

  1. ARbCl\mathrm{RbCl}
  2. BNaCl\mathrm{NaCl}
  3. CCsCl\mathrm{CsCl}
  4. DLiCl\mathrm{LiCl}

Correct answer

D. LiCl\mathrm{LiCl}

Step-by-step solution

RbCl,NaCl\mathrm{RbCl}, \mathrm{NaCl} and CsCl\mathrm{CsCl} share the same crystal structure except LiCl\mathrm{LiCl}. LiCl\mathrm{LiCl} is deliquescent. It crystalises as a hydrated LiCl. 2H2O2 \mathrm{H}_2 \mathrm{O}. Other alkali metal chlorides do not form hydrates.
