On the comparison of the polarity of dichloromethane and ethyl acetate
Taste the physical properties of the world, and the determination of polarity is related to many things. Today, if we want to discuss the difference in polarity between dichloromethane and ethyl acetate, we should study its molecular structure, atomic electronegativity and many other factors.

For dichloromethane, carbon is in the center of its molecular structure and is connected to two hydrogens and two chlorines. The electronegativity of chlorine is stronger than that of carbon, and the electron cloud is biased towards the chlorine atom, causing the molecule to produce a dipole moment.

And ethyl acetate, its structure contains an ester group. The oxygen of carbonyl and the oxygen of alkoxy are both strong electronegativity. However, its molecular structure is more complex than that of dichloromethane, and the distribution

Looking at dichloromethane, due to the strong electronegativity of the chlorine atom, the molecular polarity vector is more concentrated in the direction of the chlorine atom. Although ethyl acetate contains strongly electronegative oxygen atoms, the spatial extension of its molecular structure makes the polarity vector distribution more dispersed.

Therefore, in general, the polarity of dichloromethane is stronger than that of ethyl acetate. Because the molecular structure of dichloromethane is relatively simple, the electronegativity of the chlorine atom is significant, and the polarity vector is concentrated; while the structure of ethyl acetate is complex, and the polarity vector is scattered, weakening its overall polarity. The polarity of the two is really a corner of the exploration of chemical properties. However, in many chemical applications, this polarity difference has far-reaching implications. Experimental operations such as extraction and separation need to be carefully observed
