Which one of the following pairs of substances on reaction will not evolve $H_{2}$ gas?

Options:

Answer:

Solution:

Copper does not react with dilute HCl because copper is less reactive than hydrogen. Therefore, it cannot displace hydrogen from the acid to form $H_{2}$ gas. Iron reacts with steam and $H_{2} S O_{4}$ to produce $H_{2}$ gas. Sodium reacts with ethyl alcohol to produce $H_{2}$ gas and sodium ethoxide.
