Question

When 3,3-dimethyl-2-butanol is heated with H3PO4, what are all the minor and major product

Answer 1

The major product is 3,3-dimethylbut-1-ene.

• Alcohol is dehydrated when it loses water while being converted from an alcohol to an alkene. The loss of a hydrogen next to the intermediate carbocation is another way that this reaction takes place. A catalyst for dehydration is an acid, such as sulfuric or phosphoric acid.
• Similar mechanisms that create a carbocation by the loss of water are used in all processes. The stability of the carbocation, which is stabilised by the favourable inductive effects of alkyl groups, and the stability of an alkene, which is stabilised by having more substituents, will determine the primary product.
• Because there are no neighbouring H's on C2, the intermediate carbocation cannot undergo an H-shift to produce a more stable carbocation, and an H-shift with C1 will result in a primary carbocation that is less stable. There can only be one product produced as a result.

Hence, the major product is 3,3-dimethylbut-1-ene.
