Here are the essential concepts you must grasp in order to answer the question correctly.
Infrared (IR) Spectroscopy
IR spectroscopy is a technique used to identify functional groups in organic compounds by measuring the absorption of infrared light. Different bonds absorb characteristic frequencies of IR radiation, allowing for the identification of specific functional groups. In the context of the reaction, the presence or absence of specific peaks corresponding to NH2 groups or carbonyls can indicate whether the reaction has occurred.

Purification Techniques
Purification techniques, such as recrystallization or chromatography, are essential for isolating the desired product from a reaction mixture. After the reaction, it is crucial to ensure that unreacted reagents, like hydrazine (NH2NH2), are removed. The effectiveness of these techniques can be assessed through subsequent analytical methods, such as IR spectroscopy or NMR, to confirm the absence of impurities.

Functional Group Analysis
Functional group analysis involves identifying specific groups of atoms within a molecule that determine its chemical reactivity and properties. In this reaction, the conversion of a carbonyl compound to an amine derivative involves the disappearance of the carbonyl (C=O) and the appearance of new functional groups, such as NH2. Understanding these changes is crucial for confirming the reaction's completion and the removal of starting materials.
