Aluminum will react aqeous NaOH to give sodium aluminate with rapid evolution of hydrogen gas

2Al+ 2NaOH +2H₂O →2NaAlO₂ + 3H₂

Zinc reacts with it to form sodium zincate with the evolution of hydrogen gas

Zn + 2H₂O + 2NaOH →Na₂Zn(OH)₄ + 3H₂

Tin reacts with sodium hydroxide solution forming sodium stannate and hydrogen gas

Sn + 2NaOH + 4H₂O→Na₂Sn(OH)₆ + 2H₂

Iron shows reaction with alkalis since it doesn't have any amphoteric properties therefore, the answer is D

the answer is not correct,Iron(Fe)is the correct answer not Aluminum(Al)

the correct answer is d, the rest will react to evolve hydrogen gas while iron will not

Because they are all amphoteric so they can react with alkaline solutions but iron is not amphoteric

The metal that cannot replace hydrogen from alkaline solutions is A. Aluminium. This is because aluminium is less reactive than zinc, tin, and iron. Therefore, it cannot displace hydrogen from alkaline solutions under normal conditions.
