Why tertiary alcohols react less rapidly...

Why tertiary alcohols react less rapidly with metallic sodium than do primary alcohols ?

Text Solution

Verified by Experts

The correct Answer is:
The `+I.E`. Of three methyl groups on central C-atom of tert-butyl alcohol makes is partially negative with the result that it pushes the electron pair of `-OH` bond towards H-atom and thus H-atom is not replaced easily.

Which compound is tertiary alcohol ?

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 ?
