Question

Assertion (A): Transition metals have high enthalpy of atomization. Reason (R): This is because transition metals have low melting points.

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
• B. Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
• C. Assertion (A) is true, but Reason (R) is false
• D. Assertion (A) is false, but Reason (R) is true.

Hint:

High enthalpy of atomization in transition metals results from strong metallic bonding, which also contributes to high melting and boiling points.

Answer 1

The Correct Option is C

Transition metals have high enthalpy of atomization because of the strong metallic bonding and extensive d-orbital interactions. However, the melting points of transition metals are generally high, not low, making the given reason false.
