"Tiangong Kaiwu" was written by Song Yingxing in the Ming Dynasty, using ancient classical Chinese as a carrier, detailing all kinds of process technology and production experience. Today, based on this style, I answer your inquiry about "5,6-dihydro-2-methyl-benzo [3,2-c] furan, 4-chloro-2-methyl-geometry of physical properties".
This 5,6-dihydro-2-methyl-benzo [3,2-c] furan, 4-chloro-2-methyl, its form is either liquid or solid, depending on the surrounding temperature and pressure conditions. Its color may be nearly colorless, or slightly light yellow, clear and with a certain transparency.
Smell it, or emit a unique smell, or fragrant, or pungent, all due to the characteristics of its molecular structure. As for the melting point, the melting point, from solid to liquid, needs to be suitable for heat to break the attractive force between molecules; when the boiling point, from liquid to gaseous, also depends on energy supply. These two values vary according to the purity of the substance and environmental conditions.
In terms of solubility, organic solvents, such as ethanol, ether, etc., may have good dissolution performance. Due to the principle of "similar miscibility", their molecules are compatible with the forces between organic solvent molecules. However, in water, its molecular polarity may be different from that of water molecules, and its solubility may not be good.
In terms of density, it is lighter or heavier than water, depending on the type, number and spatial arrangement of the constituent atoms. Its density value is one of the important parameters for identifying this substance.
Furthermore, this substance may have a certain chemical activity due to the specific functional groups in the molecule. Chlorine atoms, methyl groups and benzofuran structures can cause it to participate in various chemical reactions, or nucleophilic substitution, or addition reactions, depending on the reaction conditions and the properties of the reactants.
In summary, the physical properties of 5,6-dihydro-2-methyl-benzo [3,2-c] furan and 4-chloro-2-methyl are characterized by morphology, color, odor, melting point, solubility, density and chemical activity, and are affected by factors such as environment and purity.

The chemical properties of this compound are quite complicated.
Cyanyl group has strong electron-absorbing properties, which makes the electron cloud of this compound different. It can participate in a variety of reactions, such as nucleophilic substitution reactions. Due to the presence of cyanyl groups, the electron cloud density of ortho and para-sites decreases, but under suitable conditions, it can still attract nucleophilic reagents to attack.
Pyridine ring is an aromatic structure. The lone pair of electrons of the nitrogen atom does not participate in the conjugation, so that the electron cloud density of the pyridine ring is uneven, the electron cloud density of the nitrogen atom is relatively low in the adjacent and para-position, and the meta-position is relatively high. This characteristic makes the pyridine ring can undergo electrophilic substitution reaction, and the substitution check point is mostly in the meta-position.
As for the substituents of 4-bromine and 2-methyl, they also have their own effects. Bromine atom has strong electronegativity and is an ortho-para-position group. Although its electron-absorbing effect reduces the electron cloud density of the benzene ring, it stabilizes the intermediates of the ortho-para-position substitution products to a certain 2-Methyl as the power supply group can increase the electron cloud density of the benzene ring, especially in its ortho-para-position, making this region more prone to electrophilic substitution reactions.
This compound may undergo many reactions. Under basic conditions, the cyano group or hydrolysis into carboxyl groups; bromine atoms can be replaced under the action of nucleophiles. At the same time, the pyridine ring can react with protonic acids to form salts, changing its physical and chemical properties. In organic synthesis, according to the activity of each part, through suitable reaction conditions, more complex organic molecular structures can be constructed.
