Answer 2

The incorrect statement is: A compound retains the physical properties of its constituent elements.

• The different atoms are chemically bonded with each other to form a compound. The retaining of the physical properties is only possible when the constituents are physically mixed. But, as mentioned before, the constituent elements are chemically bonded, which left no scopes for retaining the physical properties of the constituent elements.
• Hence, the statement, "a compound retains the physical properties of its constituent elements", is completely false about the compounds.
• The other two statements which are mentioned about the compounds are true.
