Li shows anomalous behaviour to other alkali metals which can be attributed to its high charge density. Select the correct statement(s) about lithium.

Options

  1. ALithium hydroxide decomposes upon heating
  2. BLithium does not form the nitride on reaction with N ₂
  3. CLithium does not form the solid hydrogen carbonate
  4. DLithium chloride does not crystallise as a hydrate

Correct answer

C. Lithium does not form the solid hydrogen carbonate

Step-by-step solution

Answer (A, C) Li forms Li ₃ ~N and LiCl precipitates as LiCl .2 H ₂ O .
