First, the appearance, at room temperature, or a light yellow to light brown crystalline solid, the quality is stable, which is due to intermolecular forces and structural characteristics. Looking at its color, due to intramolecular electron transitions, especially the interaction of nitro groups with conjugated systems, it absorbs specific wavelengths of light, resulting in this color.
The melting point, after measurement and experiment, is about 70-80 degrees Celsius. The chlorine, fluorine atoms and nitrovinyl groups in the molecule interact with hydrogen bonds by van der Waals force, so that the molecules are arranged in an orderly manner, and a specific energy is required to destroy the lattice. The melting point is in this range.
Its boiling point also has characteristics, at atmospheric pressure, about 300 degrees Celsius. The molecule contains benzene ring, halogen atom and nitrovinyl group, complex structure, strong intermolecular force, high temperature is required to overcome the attractive force, and it changes from liquid to gaseous state.
In terms of solubility, it is slightly soluble in water. Water is a polar solvent. Although this compound contains polar group nitro, the benzene ring is a non-polar structure, the overall polarity is limited, and the interaction with water is weak, making it difficult to dissolve in water. However, in organic solvents such as dichloromethane, chloroform, and toluene, the solubility is quite good. These organic solvents are similar in structure to this compound, and can dissolve with each other according to the principle of "similar miscibility".
Density is also an important physical property, the relative density is slightly higher than that of water, about 1.4-1.5 g/cm ³. Due to the large relative atomic mass of chlorine and fluorine atoms in the molecule and the compact structure, the unit volume mass is larger than that of water.
The physical properties of this compound provide a key basis for its synthesis, separation, purification and application. During synthesis, the reaction conditions and separated products are controlled according to the melting point and boiling point; when applying, the solvent and reaction medium are selected according to the solubility.

First talk about its halogen atom, the existence of chlorine and fluorine atoms changes the polarity of the molecule and affects its physical properties such as solubility and boiling point. The activity of chlorine atoms is moderate, and in the nucleophilic substitution reaction, it can be replaced by a variety of nucleophilic reagents, such as reacting with sodium alcohol, which can form corresponding ether compounds; the electronegativity of fluorine atoms is large, which has a significant impact on the density of the benzene ring electron cloud, which makes the benzene ring electron cloud shift to the fluorine atom, and then affects the reactivity of other positions on the benzene ring.
Furthermore, the (Z) -2 -nitrovinyl functional group is also the key. Nitro has strong electron absorption, which makes the double-bond electron cloud biased towards nitro, which reduces the density of the double-bond electron cloud and makes it vulnerable to the attack of electrophilic reagents. At the same time, the existence of nitrovinyl makes the molecule have a certain conjugate system, and the conju For example, this conjugated system can make the compound have a specific absorption peak in the ultraviolet-visible spectrum.
From the perspective of reactivity, under basic conditions, the chlorine atoms of the compound are prone to elimination reactions to generate products containing unsaturated bonds; nitro vinyl double bonds can be added, such as with hydrogen halide. Due to the electron-absorbing action of nitro groups, the addition direction follows the Markov rule, and hydrogen atoms are added to double-bonded carbon atoms containing more hydrogen.
