Question

Given below are two statements:

Statement I: Both CaCl₂.6H₂O and MgCl₂.8H₂O 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:

Options

• Statement I is true but statement II is false.

• Both Statement I and Statement II are false.

• Statement I is false but statement II is true.

• Both Statement I and Statement II are true.

Answer 1

Both Statement I and Statement II are false.

Explanation:

\[\ce{CaCl2.6H2O ->[\Delta] CaCl2 + 6H2O}\]

\[\ce{MgCl2.6H2O ->[\Delta] MgCl (OH) + H2O}\]

BeO is an amphoteric alkaline earth metal, while the others are basic oxides.
