Which is produced by the dehydration of primary alcohols? An alkene is produced when dehydration of an alcohol is performed. This allows for the formation of an alkene without any in-between formation of an unstable carbocation.

Primary alcohols dehydrate through the E2 mechanism. The hydroxyl oxygen donates two electrons to a proton from sulfuric acid (H 2 SO 4 ), forming an alkyloxonium ion. Then the conjugate base, HSO 4 – , reacts with one of the adjacent (beta) hydrogen atoms while the alkyloxonium ion leaves in a concerted process, forming a double bond.

Tertiary alcohols are easy to dehydrate but on the other hand, primary alcohol dehydration is very tough. The dehydration of secondary and tertiary is known as an E1 reaction (it’s a two-step mechanism), whereas the dehydration of primary alcohol is known as E2 reaction (it’s a one-step mechanism) because it is difficult to form primary carbocations.

What is Dehydration of Alcohols? Alcohol upon reaction with protic acids tends to lose a molecule of water to form alkenes. These reactions are known as dehydrogenation or dehydration of alcohols. It is an example of an elimination reaction. Its rate varies for primary, secondary and tertiary alcohols.

Notes: Dehydration of Alcohol An alcohol can be converted to an alkene using Sulfuric or Phosphoric acid. Primary acids are difficult to dehydrate and must be heated to high temps. Secondary alcohols will dehydrate at somewhat lower temps. Tertiary alcohols will dehydrate slightly above room temp.

The oxidation of p rimary alcohols leads to the formation of either aldehydes or carboxylic acids. It depends on the reagents used during the chemical reaction. Strong reagent converts primary alcohols to carboxylic acids and mild reagents converts primary alcohols to aldehydes.

When alcohol reacts with protic acids it tends to lose a molecule of water in order to form alkenes. These reactions are generally known as dehydration of alcohols. It is a basic example of an elimination reaction. The rates differ for the primary, secondary and tertiary alcohols.
