To determine the decreasing order of reactivity of sodium metal towards primary, secondary, and tertiary alcohols, we can follow these steps: ### Step 1: Understand the Structure of Alcohols - **Primary Alcohol**: An alcohol where the hydroxyl (-OH) group is attached to a carbon that is connected to only one other carbon (R-CH2-OH). - **Secondary Alcohol**: An alcohol where the hydroxyl group is attached to a carbon that is connected to two other carbons (R1-CHOH-R2). - **Tertiary Alcohol**: An alcohol where the hydroxyl group is attached to a carbon that is connected to three other carbons (R1-R2-R3-C(OH)-R4). ### Step 2: Analyze Acidity of Alcohols ...

Alcohols undergo acid catalysed elimination reactions to produce alkenes. Because water is lost in the elimination , this reaction is called dehydration reaction. Secondary and tertiary alcohols always give E1 reaction in dehydration. Primary alcohols whose beta -carbon is branched also give E1 reaction. The reactivity of alcohol for elimination reaction is tertiary alcohol > secondary alcohol > Primary alcohol. Which of the following dehydration product (major ) is incorrect ?
