The dehydration of the alcohol functional group is a widely used reaction in organic chemistry. The mechanism is generally accepted to always operate via an step-wise process. The mechanism process will always produce (after dehydration) a style alkene as major product. The driving force for the production of this style alkene product is generally going to be determined by stability of the .
