Dehydration reactions aren't electrophilic, they're elimination reactions, and, like with hydration, have their own mechanisms separate from electrophilic reactions
But we use an acid in both the reactions, and the reaction is initiated by an H(with a slightly positive charge) atom attached to the acid. Will this, then, not be an electrophilic reaction?
Or is it that only addition/substitution reactions can be electrophilic or nucleophilic, and elimination can not be?
If so, reason please. :D
Cause we're still using an acid where the H atom can be considered as an electrophile.
