Which of the following metals cannot displace hydrogen grom nonoxidizi

1.	Which of the following metals cannot displace hydrogen grom nonoxidizing acids ? `Pb` (ii) `Sn` (iii) `Ni` (iv) `Zn`.A. (i), (ii), (iii)B. (ii), (iii), (iv)C. (i), (ii), (iii) (iv)D. (i), (ii)
Answer» Correct Answer - C Many metals like Pb, Sn,Ni, Co, and `Cd` which do not react with water are capable of displacing hydrogen from non oxidizing acids : ` Cd(s) + 2HCl(aq.) rarr CdCl_2(aq.) + H_2 (g)` `Sn(s) + 2HCl(aq.) rarr SnCl_2(aq.) + H_2(g)` These metals lie above H in the activity series.
