Give the formula of a product (derived from the first-named substance) that may be formed in the following reactions. (Note, in the example that any lower oxidation state compound is possible: but not any higher one. Some are more probable than others.)
Example: H2SO3 is treated with a reducing agent. S, S22-, H2S
HClO2 is treated with a reducing agent.
Provide a structure for the following compound: C9H10O3; IR: 2400-3200, 1700, 1630 cm-1; 1H NMR: ? 1.53 (3H, t, J = 8 Hz); ? 4.32 (2H, q, J = 8 Hz); ? 7.08, ? 8.13 (4H, pair of leaning doublets, J = 10 Hz); ? 10 (1H, broad, disappears with D2O sha..
