and
An acidic liquid has a broad band at 3300 cm
a sharp band at 1710 cm in the infrared spectrum.
One mole of this unknown reacts with one mole of
NaOH. The ¹H NMR spectrum shows three peaks
in the ratio 2 : 2 : 1. Microanalysis gave C, 33.2 %;
H, 4.6%; C1, 32.7%.
Deduce the structure of the unknown.
Spell out the full name of the compound.

The product formed upon oxidation of an unknown
organic compound with chromic acid has the molecular
formula, C5 H10O. The ¹H NMR spectrum of the
product is shown below and its IR spectrum has a strong
band at 1700 cm-¹.(Figure 1)
Using this information, deduce the structure of the product and
hence the structure of the unknown compound.
