The alkaline earth metal nitrate that does not crystallise with molecules is:

Options

  1. AB a N O 3 2
  2. BS r N O 3 2
  3. CM g N O 3 2
  4. DC a N O 3 2

Correct answer

A. B a N O 3 2

Step-by-step solution

B a   N O 3 2 does not have any water of crystallization. This happens because the large size of B a + 2 leads to poor polarizing power and hence, unable to attract water molecules effectively.
