UPSC NDA-2 – 2022
The correct reactivity series with water among the given metals is Zinc > Iron > Lead > Copper.
The reactivity series lists metals in order of decreasing reactivity. Metals higher in the series are more reactive. In the given options, Zinc is more reactive than Iron, which is more reactive than Lead, which is more reactive than Copper.
Highly reactive metals like Potassium and Sodium react vigorously with cold water. Moderately reactive metals like Magnesium and Zinc react with hot water or steam. Less reactive metals like Iron, Lead, Copper, Silver, and Gold do not react with water or steam under normal conditions, or react very slowly (like Iron rusting in the presence of water and oxygen). The general order of reactivity involving water reaction is K > Na > Ca > Mg > Al > Zn > Fe > Pb > H > Cu > Ag > Au. Comparing the given metals (Zn, Fe, Pb, Cu) shows the order Zn > Fe > Pb > Cu.
