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:
A
Statement-I is correct but Statement-II is false.
B
Statement-I is incorrect but Statement-II is true.
C
Both Statement-I and Statement-II are true.
D
Both Statement-I and Statement-II are false.
Detailed Solution
Hydrated chlorides and bromides of Ca, Sr and Ba are predominantly ionic, and on heating they undergo dehydration (loss of water of hydration), not hydrolysis — so Statement I is false. Hydrated chlorides and bromides of Be and Mg, being more covalent, actually undergo hydrolysis on heating (not dehydration) — so Statement II is also false.
