34. Normally, heating an initial aldol product (the β-hydroxyaldehyde) causes dehydration. However, heating the compound below with base does not cause dehydration, but rather, decomposition to form 2-ethylbutanal. This is because: (A) There are no protons β to the carbonyl. (B) There are no protons adjacent to the OH, and the dehydration reaction requires E1 conditions. (C) There are no protons α to the carbonyl, and aldol condensations are reversible. (D) Heating any organic compound above room temperature causes decomposition. (E) None of these is true.
