Given below are two statements: Statement I : Hydrated chlorides and bromides of Ca , Sr and Ba on heating undergo hydrolysis. Statement II : Hydrated chlorides and bromides of Be and Mg on heating undergo dehydration. In the light of the above statements, choose the correct answer from the options given below :

Options

  1. ABoth Statement I and Statement II are true.
  2. BBoth Statement I and Statement II are false.
  3. CStatement I is correct but Statement II is false.
  4. DStatement I is incorrect but Statement II is true.

Correct answer

B. Both Statement I and Statement II are false.

Step-by-step solution

Since hydrated chlorides and bromides of Ca , Sr and Ba are ionic in nature they will get dehydrated on heating and hydrolysis will not take place, while chloride and bromide of Be and Mg has covalent nature hence, they will get hydrolysed.
