Compound A, with a molecular formula C3H4, shows two singlets in its 1H NMR spectrum (with a ratio 3 : 1). Compound B is formed when compound A undergoes an acid-catalyzed hydration. Compound B also gives a positive iodoform test, and shows a singlet in its 1H NMR spectrum. Determine the structures A and B.
