Answer 2

Both Assertion and Reason are true and Reason is the correct explaination of assertion.

• Generally all metal oxides are just basic in nature. But few exceptions like zinc can react with both acids as well as bases. Such type of metals are called as Amphoteric oxides. Hence, the given assertion is true.
• The reason behind the fact is that the electronegativity difference of both zinc and oxygen is very small.
• This is the reason why zinc can react with both acids as wells as bases. Hence, the given reason is correct explaination of assertion.
