WebWhen you dehydrate an alcohol, you remove the -OH group, and a hydrogen atom from the next carbon atom in the chain. With molecules like butan-2-ol, there are two possibilities when that happens. That leads to these products: The products are but-1-ene, CH 2 =CHCH 2 CH 3, and but-2-ene, CH 3 CH=CHCH 3. WebThe production of alkene occurs when alcohol is dehydrated. The following is a simple structural equation for alcohol dehydration: C2H5OH → C2H4 +H2O. Elimination …
