Question

Given below are two statements:
Statement $I:$ Both $CaC{l}_2.6H_{2}O$ and $MgC{l}_2.8H_{2}O$ undergo dehydration on heating.
Statement $II:$ $BeO$ is amphoteric whereas the oxides of other elements in the same group are acidic.
In the light of the above statements, choose the correct answer from the options given below:

• A. Statement $I$ is true but statement $II$ is false
• B. Both statement $I$ and statement $II$ are false
• C. Statement $I$ is false but statement $II$ is true
• D. Both statement $I$ and statement $II$ are true

Answer 1

The correct option is B Both statement $I$ and statement $II$ are false

The dehydration of $CaC{l}_2.6H_{2}O$ can be achieved on heating whereas $MgC{l}_2.8H_{2}O$ on heating suffer hydrolysis.
Among alkaline earth metal $BeO$ is amphoteric and rest are basic oxide.
