Question

preperation of ethyl alcohol from acetaldehyde​

Answer 1

Answer:

The first step is endothermic and produces acetaldehyde. The second step is the hydrogenation of the acetaldehyde to form the ethanol. This step is faster and is exothermic. Unlike the hydrogenation of acetic acid, the hydrogenation of acetaldehyde is not believed to involve an endothermic step.
