WebUnimolecular dehydration of C 3 -C 4 alcohols follows the same mechanism as that for ethanol and involves inhibition by dimers. Deuterated alcohols show a primary kinetic isotope effect for unimolecular dehydration, implicating cleavage of a C-H bond (such as the C β -H bond) in the rate-determining step for olefin formation on γ-Al 2 O 3. WebOct 14, 2024 · Other dehydration causes include: Diarrhea, vomiting. Severe, acute diarrhea — that is, diarrhea that comes on suddenly and violently — can cause a tremendous loss of water and electrolytes in a short amount of time. If you have vomiting along with diarrhea, you lose even more fluids and minerals. Fever.
