Question

A non-metal X reacts with Y to form a covalent compound XY. Identify the incorrect statement regarding compound XY.

• A. XY will undergo dissociation in water.
• B. XY can be a good conductor of electricity.
• C. XY will give out ions in aqueous solution.
• D. XY will undergo ionisation in water.

Answer 1

The correct option is A XY will undergo dissociation in water.

• A non-metal X reacts with Y to form a covalent compound XY. Hence, the compound XY is a non ionic compound.
• Statement 1: XY will not undergo dissociation reaction since it is a non-ionic compound. So, statement 1 is incorrect.
• Statement 2: XY will undergo ionisation reaction since it is a non ionic compound. So, statement 2 is correct.
• Statement 3: Non-ionic compounds can be a good conductor of electricity. So, statement 3 is correct.
• Statement 4: Non-ionic compounds will give out ions in aqueous solution. So, statement 4 is correct.
• So, the answer is option A.
