### Experiment 6: IR Spectroscopy#### Description of the Reaction**Chemical Reaction:**The provided diagram illustrates the transformation of a cyclohexanol compound into a cyclohexanone compound through an oxidation reaction facilitated by sodium hypochlorite (NaOCl) in the presence of acetic acid (AcOH) and elevated temperatures (45-50°C).**Reactants:**- **Starting Material:** Cyclohexanol (Cyclohexane ring with an -OH group attached).- **Reagents:** Sodium hypochlorite (NaOCl) and Acetic Acid (AcOH).**Conditions:**- Temperature range: 45-50°C.**Product:**- **End Material:** Cyclohexanone (Cyclohexane ring with a ketone group attached, -C=O).#### Purpose of the ExperimentThe purpose of this experiment is to use Infrared (IR) Spectroscopy to confirm the successful conversion of cyclohexanol to cyclohexanone. IR Spectroscopy allows for the identification of various functional groups based on their characteristic vibrational frequencies.#### Expected IR Spectral Changes:- **Cyclohexanol:** - Broad O-H stretch around 3200-3550 cm⁻¹. - Aliphatic C-H stretches around 2850-2950 cm⁻¹. - **Cyclohexanone:** - Sharp C=O stretch around 1700-1750 cm⁻¹. - Aliphatic C-H stretches around 2850-2950 cm⁻¹ (similar to cyclohexanol but without the broad O-H stretch).The absence of the broad O-H stretch and the appearance of a sharp C=O stretch in the IR spectrum of the product would confirm the oxidation process has taken place, converting the alcohol to a ketone.#### ConclusionIn summary, this experiment demonstrates the utility of IR spectroscopy in identifying functional groups and monitoring the progress of chemical reactions such as the oxidation of an alcohol to a ketone. By analyzing the IR spectra before and after the reaction, one can confirm the successful conversion of the starting material to the desired product.

IR spectroscopy mainly used for the determination of functional groups present in molecules.
