They react with sulfides, oxidizing agents, aldehydes, and cyanides. They corrode rapidly on contact with the air, becoming coated with white oxides and peroxides. As a practical matter, most other organic compounds, including ethers, are wet enough (carry enough water as an impurity) to cause heating and liberation of gases in contact with alkali metals.

Metal reactivity with hot water VS HCL - Chemistry Stack …
Does being able to react with hot water take more metal reactivity than being able to react with HCl? To me, it seems like a metal would need to be more reactive to be able to react with hot water since HCl is a very strong acid and so should theoretically be able to react with more metals, but I am not so sure.
