3. Isomerism Absence of the existence of 1,2 disubstituted isomers in benzene compounds provides more evidence for a delocalised ring system. For example, if benzene were to have an alternating double and single bond structure, 1,2 dichlorobenzene could exist with a double bond, or a single bond between the carbon atoms holding the chlorine atoms.

1/6/1993· In the series of 1- X ,4- Y -disubstituted benzenes, where X is a variable substituent (an atom or functional group) and Y is a fixed substituent (a composite group which can conjugate with the benzene ring), the dihedral angle between the benzene ring and the plane of the Y substituent can depend on the variable substituent X.
Orientation in Electrophilic Substitution in Benzene
1/9/2021· Electrophilic Substitution in Benzene When an electrophilic substitution reaction occurs on the benzene ring, we get just one monosubstituted benzene due to the fact that all the six placements in the ring are equivalent. Nonetheless, the addition of a second group into the ring may give three isomeric disubstituted products, ortho, meta, and para.

Identifying the Name of a Disubstituted Benzene Derivative
So let’s look at another way to name disubstituted benzene derivatives. When the two substituents are attached to carbon atoms one and two of the benzene ring, we can use the prefix ortho- or o- to describe the relative position of the two substituents. When the substituents are attached to carbon atoms one and three, we use the prefix meta- or m-.
