Step-by-step solution

The major product [ R ] in the following sequence of reaction is :

The major product [ R ] in the following sequence of reaction is :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.The order of the ease of dehydration of alcohols is: tertiary > secondary > primary.
