Suppose 1 M H₂SO4 were substituted for the concentrated H₂SO4. Would the yield of acetylsalicylic acid be increased, decreased, or unaffected by the substitution? Explain.
Formaldehyde, H2C=O, is known to all biologists because of its usefulness as a tissue preservative. When pure, formaldehyde trimerizes to give trioxane, C3H6O3, which, surprisingly enough, has no carbonyl groups. Only one monobromo derivative (C3H5BrO3) of trioxane is possible. Propose a structure for trioxane.
