### Step-by-Step Solution: 1. **Understanding Ether Preparation**: Ethers can be synthesized through the acid dehydration of alcohols. This involves the removal of water (H2O) from alcohols in the presence of an acid catalyst. 2. **Mechanism Overview**: The mechanism begins with the protonation of the alcohol, forming a positively charged intermediate. For example, when ethanol (CH3CH2OH) is protonated, it forms CH3CH2OH2^+. 3. **Nucleophilic Attack**: Another molecule of alcohol acts as a nucleophile and attacks the carbon atom of the protonated alcohol. This leads to the formation of an ether and the elimination of a water molecule. ...

What is the order of dehydration of primary, secondary and tertiary alcohols?

Acidic dehydration of the following alcohols is in the order :

Alcohols undergo acid catalysed elimination reactions to produce alkenes. Because water is lost in the elimination , this reaction is called dehydration reaction.
