The polarity of butyl acetate is related to its molecular structure and charge distribution, which is the essence of chemistry. To distinguish the polarity of butyl acetate (Butyl Acetate) or not, it is necessary to study the shape of its molecule. The molecule of butyl acetate is formed by connecting acetate and butyl. In acetate, carbonyl carbon and oxygen atoms are connected by double bonds, and oxygen has strong electronegativity, resulting in a partial negative charge in the electron cloud in the carbonyl region; butyl is alkyl, and the electronegativity difference between carbon and hydrogen is small, and the electron cloud distribution is relatively uniform.

Looking at the whole, the molecular structure is non-centrosymmetric. The polarity of carbonyl is not completely offset by butyl. Therefore, from the attitude of uneven distribution of molecular charges, butyl acetate shows polarity.

However, compared with many strongly polar compounds, the existence of butyl weakens its polarity to a certain extent. The carbon chain of butyl has a certain shielding and buffering effect, so that the polarity of butyl acetate is not strong.

In summary, butyl acetate is a polar molecule, but its polarity is weak. This property has a significant impact on many chemical processes, such as dissolution and extraction, and cannot be ignored.
