Comparison of polarity between hexane and ethyl acetate
The polarity of the male compound is related to its molecular structure and charge distribution, and has a significant impact on chemistry, such as the solubility, separation and purification of substances. This article wants to analyze the polarity difference between hexane and ethyl acetate in detail.

Hexane belongs to the class of alkanes, and its molecular structure is a straight chain, which is connected by a covalent bond between carbon and hydrogen atoms. The electronegativity difference between carbons and hydrocarbons is small, the carbon-carbon bond is also a non-polar bond, and the molecular structure is symmetrical, and the charge distribution is uniform. Therefore, the overall polarity of hexane is very small, which can be regarded as a non-polar solvent.

In contrast, the molecular structure of ethyl acetate contains ester groups (-COO -). In this ester group, the oxygen atom of the carbon-oxygen double bond has strong electronegativity and strong attractiveness to electrons, causing the electron cloud to bias towards the oxygen atom, causing the region to be partially negatively charged; while the carbon atom connected to it is partially positively charged. In this way, the charge distribution in the molecule of ethyl acetate is uneven, showing a certain polarity.

To sum up, the molecular structure of hexane is symmetrical, the charge distribution is uniform, and the polarity is weak; ethyl acetate has a certain polarity because it contains ester groups. Therefore, it can be seen that the polarity of hexane is less than that of ethyl acetate, and the polarity of non-hexane is greater than that of ethyl acetate. It is clear that the difference in polarity between the two is of great help in the selection of solvents and the properties of matter in chemical experiments and
