Question

Assertion (A): Metals are generally good oxidizing agents.

Reason (R): Metals are electropositive in nature.

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

Answer 1

The correct option is D

A is false and R is true

Explanation for the correct option:

• The assertion given in the question is Metals are generally good oxidizing agents.
• The reason is Metals are electropositive in nature.
• The reason is correct but the assertion is false.
• As metals are good reducing agents because they can easily donate their valence electrons and gets oxidize. Hence metals are reducing agents.
• Metals are electropositive in nature because they have the tendency to donate electrons due to which they acquire positive charge. For example, Sodium atom ($\mathrm{Na}$) has 1 valence electron, after donating 1 electron it becomes Sodium ion (${\mathrm{Na}}^{+}$).

Therefore, the correct option is (D).
