Both terms name the same chemical compound that has the chemical formula C3H8O. Thus, it is an alcoholic compound having the羟functional group. Here, we will explain the reasons behind each name, in addition to the structure, properties, and uses of this compound,
What is 2 Propanol?
2 propanol is the IUPAC name for the compound having the chemical formula C3H8O. Hence, 2 propanol is an alcohol that contains a hydroxyl group (-OH) as its functional group. It exists as a colourless liquid at room temperature, and it is highly flammable as well. Moreover, it also has a strong odour.
When considering the chemical structure, it has three carbon atoms as a chain, and the hydroxyl group attaches to the middle carbon while all the other vacant positions contain hydrogen atoms. It is thus, secondary alcohol and is a structural isomer to 1-propanol.
Some chemical and physical information about the compound are as follows;
- Molar mass is 60.1 g/mol.
- Appearance is colourless.
- The boiling point is 82.6 °C.
- Miscible with water, ethanol, ether and chloroform.
- Becomes increasingly viscous with decreasing temperature.
What is Isopropanol?
异丙醇化合物的常用名哈ving the chemical formula C3H8O. The IUPAC name of this compound is 2 propanol, and it is also common asisopropyl alcohol.
It derives the common name from its structure; the molecule is an alcohol, and it has an isopropyl group linked to a hydroxyl group that makes it a secondary alcohol.
What is the Difference Between 2 Propanol and Isopropanol?
Both terms 2 propanol and isopropanol describe the same chemical compound that has the chemical formula C3H8O; only the terminology is different from each other. Specifically, 2 propanol is the IUPAC name for the compound whereas isopropanol is the common name. Therefore, other than the application of the term, there is no difference between 2 propanol and isopropanol.
此外，我们在日常生活中使用的另一个通用名称是异丙醇。尽管这三个术语都称为相同的化合物，但它们根据化合物的化学结构获得了名称。2丙醇之所以得名，是因为羟基附着在2ndcarbon of a propane molecule. On the other hand, isopropanol or isopropyl alcohol got its name because of the linkage of an isopropyl group to a hydroxyl group.
概括– 2 Propanol vs Isopropanol
Both terms 2 propanol and isopropanol describe the same chemical compound. Thus,only the terminology is different. Hence, the key difference between 2 propanol and isopropanol is that the 2 propanol is the IUPAC name for the compound having the chemical formula C3H8O whereas the isopropanol is the common name for the same compound.
