Gold is more reactive than sodium.
The reactivity of metals increase as we go down in a group,for example-In group 1, Cesium is more reactive than sodium .
But this means that in group 11 ,Gold is more reactive than Copper,but since we have studied the reactivity series which says that Gold is less reactive than Copper.How is this possible?
Hydrogen from alcohol is displaced by sodium because sodium is more reactive than hydrogen
In alcohol, Hydrogen is displaced by sodium because sodium is more reactive than hydrogen
