Answer 2

Answer:

Disappearance of IR band at 3600 per cm  and appearance of IR band at 1710 per cm can be seen during the oxidation reaction.

Explanation:

Given IR band at 3600 cm⁻¹ disappears and appears at 1710 cm⁻¹.

• IR spectroscopy gives an information about the presence of specific functional groups.
• A particular functional group have a characteristic absorption spectrum of IR radiation around a particular range of wavelength.
• In alcohols, due to the O-H bond, a strong absorption band can be seen around 3600 cm⁻¹.
• Carbonyl compounds that contain the C=O functional group shows an absorption band around 1710cm⁻¹.
• IR spectroscopy also gives an information of chemical reactions that involves a gradual change in the functional group.
• Disappearance of IR band at 3600cm⁻¹ means the disappearance of OH bond and appearance of 1710cm⁻¹ means the formation of C=O bond.
• This happens during the oxidation of an alcohol to carbonyl compound.

Hence, the reaction is oxidation reaction.
