Question

Given below are two statements:
Statement I ; Both $CaC{l}_2\cdot 6H_{2}OandMgC{l}_2\cdot 8H_{2}O$
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 fromm the options given below.

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

Answer 1

The correct option is C Both statement I and statement II are false

$CaC{l}_2\cdot 6H_{2}O$ undergoes dehydration on heating but $MgC{l}_2\cdot 8H_{2}O$ undergoes hydrolysis on heating.

$BeO$ is amphoteric and other metal oxides of II A group are basic in nature.
Thus, both Both statement I and statement II are false
