Polarity can be a bit of a tricky subject in chemistry. Not only are a majority of the major concepts somewhat unintuitive until you have a decent understanding of chemistry as a whole. There are also a lot of nuances and exceptions that can be difficult to keep track of. However, if you want to get a deep understanding of how polarity works, you have come to the right place.  

Understanding Polarity  

 A common misconception is that a compound is either polar or nonpolar. While this is true, it is not particularly useful to know that a compound is polar unless you also know how polar it is. Polarity is not just a yes or no question, but also a how much question. Water and ethanol can both be accurately described as polar, but water is much more polar than ethanol and has many different properties as a result.  

To understand why different molecules, have different polarities, it is helpful to understand what causes polarity. Molecular structure plays an important role, with its symmetry and balance determining the overall polar nature of a molecule. Every atom has its own electronegativity. When two atoms of different electronegativities bond, the electrons will spend more time near one and less near the other.  

This creates an imbalance in charges, with the electron-dense area becoming negatively charged and the electron-light area becoming positively charged. In molecules where the molecular structure is balanced and symmetrical, these imbalances can cancel each other out. However, this is a rarity, most molecules have more complex structures that do not possess internal symmetry.  

Ethyl Acetate vs Hexane Polarity  

 Both of these chemicals are very common solvents in chemical and industrial processes. As such, understanding their polarities can be quite helpful. This chemical has an ester group, which contains one of those aforementioned imbalances. However, the rest of the molecule is nonpolar which results in it being polar, but only mildly.  

Hexane, on the other hand, is completely nonpolar. Being nothing more than a chain of similarly electronegative atoms, the individual imbalances in charges are very weak and as a whole completely cancel each other out.

Ethyl acetate is a widely used chemical in modern processes. Coffee and tea are decaffeinated through this chemical, while for perfumes it promotes high volatility to allow for quick evaporation. Given this substance’s broad range of uses, it is helpful to know some of its key properties that might be useful in other processes.  

One of the most important chemical properties of any compound is its polarity, so is our chemical polar or nonpolar?  

How Polarity Works  

 In chemistry, polarity is a measure of the electric balance of a molecule. While you might think that molecules will always have an overall neutral charge, it would not be chemistry if things did not become complex. Polarity arises when atoms bond to each other to form a molecule, protons stay in their respective atoms but electrons move around.  

When a molecule is formed, the electrons tend to concentrate on the larger atoms which contain more protons. For example, water contains one oxygen atom and two hydrogen atoms. Oxygen contains more protons than hydrogen, so the electrons in water molecules spend much more time near the oxygen atom than the hydrogen atoms. So, although water has 10 protons and 10 electrons, poles develop because the electrons favor the oxygen atom.   

Near the oxygen atom, a negative charge develops. Meanwhile, because the hydrogen atoms kept their protons but lost their electrons, a positive charge develops. In other words, a negative pole develops at the oxygen and a positive pole develops at the hydrogens. It is because of this that water is a highly polar molecule.  

Is Ethyl Acetate Polar?  

 In short: yes, ethyl acetate is polar.   

Polarity is not a binary property; molecules are not either polar or nonpolar. It is more useful to think of the property as a spectrum. Some molecules are completely nonpolar at one end, some are highly polar at the other end, and most molecules are somewhere in between.   

This chemical, although it is polar, it is not nearly as polar as water. If you made a polarity scale where water was a 10/10 for polarity and a perfectly balanced molecule like methane was a 0/10, ethyl acetate would be somewhere between a 2 and 3. While this might seem low, it is still high enough for ethyl acetate to have chemical properties inherent to polar compounds.
