Solution
Metals : 1.5 Marks
Reason : 1.5 Marks
Cu, Au, Ag and Pt are metals which can’t displace hydrogen from an acid. The reason for such a property is that these metals are placed lower in than hydrogen in the reactivity series. Since, they are less reactive than hydrogen, they cannot displace hydrogen from its compound.
