The exact refractive index of 1-Methylcyclohexene is 1.44 (nD).
Understanding the Refractive Index of 1-Methylcyclohexene
The refractive index (often denoted as nD) is a fundamental physical property of a substance, indicating how much light bends, or refracts, when it passes through the substance from a vacuum. The 'n' stands for refractive index, and 'D' refers to the sodium D-line, a specific wavelength of light (589 nanometers) commonly used for these measurements. This property is crucial for the identification and purity assessment of liquid organic compounds like 1-Methylcyclohexene.
For 1-Methylcyclohexene, a cyclic olefin with a characteristic odor, its refractive index of 1.44 signifies its optical density and how it interacts with light. This value can be precisely measured using a refractometer, a common laboratory instrument.
Key Physical Properties of 1-Methylcyclohexene
Beyond its refractive index, 1-Methylcyclohexene possesses several other important physical characteristics that define its behavior and applications. These properties are vital for chemists and researchers working with this compound.
Here's a summary of some of its key properties:
| Property | Value |
|---|---|
| Refractive Index | 1.44 (nD) |
| Melting Point | −120.4 °C (−184.7 °F; 152.8 K) |
| Boiling Point | 110 °C (230 °F; 383 K) |
| Solubility in Water | 0.052 g/kg |
Practical Significance
The refractive index, alongside other physical constants such as boiling point and melting point, serves as a fingerprint for chemical substances. In quality control and research, measuring the refractive index of a sample of 1-Methylcyclohexene can quickly verify its identity or assess its purity. Deviations from the standard value of 1.44 (nD) can indicate the presence of impurities or a different compound entirely. This non-destructive analytical technique is widely employed in various industries, from chemical manufacturing to pharmaceutical development.
