Let's talk about 2,4-dichlorophenyl first, which is replaced by chlorine atoms at the two and four positions above the benzene ring. The benzene ring is a six-membered ring structure with conjugate stability. The chlorine atom is attached to it, because of its electronegativity, it disturbs the distribution of electron clouds in the benzene ring.
Furthermore, the methoxy group, that is, the methyl group is attached to the oxygen group. The methyl group is an alkyl group, which has the effect of pushing electrons, while the oxygen group has the property of attracting electrons. The two are connected, and they also affect the electron cloud and spatial steric resistance in the overall structure.
And ethyl, which is ethane to remove the remaining group of a hydrogen atom. In the molecule, the presence of ethyl affects the size, polarity and spatial arrangement of the molecule.
1 - is a specific number, indicating a specific position. 1H - pyrazole, pyrazole is a five-membered heterocyclic ring containing two adjacent nitrogen atoms. 1H - The epihydrogen atom is attached to the nitrogen atom at the first position of the pyrazole ring.
Connect the groups according to the structure in the question, 2-linked to 2,4-dichlorophenyl, and 2-linked to ethyl containing 2,4-dichlorophenyl methoxy. In this way, the unique chemical structure of this organic compound is constructed. In its structure, the interaction of each group, or the transfer of electron clouds, or the repulsive attraction of space, together determine the physical and chemical properties of this compound.
