Which fo the following metals cannot deplace hydrogen from nonoxidizin

1.	Which fo the following metals cannot deplace hydrogen from nonoxidizing acids ? (i) `Au" "` (ii) `Pt` (iii) `Ag" "` (iv) `Cu`A. (i) , (ii), (iii)B. (ii), (iii), (iv)C. (i), (ii)D. (i), (ii), (iii), (iv)
Answer» Correct Answer - D Elements such as Sb (a metalloid) , `Cu, Hg, Ag, Pt`, and `Au` (metals ) which lie below H in the activity series cannot displace H from non-oxidizing acids.
