1) Three organic compounds are isomers. They each have the molecular
formula C3H6O2. The three isomers react with dilute aqueous sodium
hydroxide in three different reactions according to the following equa-
tions:
Reaction A: C3H6O2 + NaOH → C3H5ONa + H₂O
Reaction B: C3H6O2 + NaOH → CHO₂Na+ C₂H6O
Reaction C: C3H6O2 + NaOH → C₂H3O2Na+ CH₂O
Identify and write the full structural formula of the three isomers in
each equation.
2) Compound P has composition by mass: C 40.0%, O. 53. 3%, and H
6.67%.
a) Show that the empirical formula of P is CH₂O.
b) P reacts with acidified potassium dichromate (VI) to produce or-
ganic compound Q. Suggest a possible structural formula for Q.
