(The course of compounds, which consists of benzene or substituted derivative that benzene)

Benzene

There is a class of hydrocarbons, that is characterized by a high level of unsaturation and also unusual stability. The many important and also common member that this course is benzene (C6H6). The formula is represented in several ways:

*
*
*
Expanded structure formula with condensed heat angle formula.

You are watching: Name each of the following disubstituted benzenes.

This representation is no as common in chemistry references, yet is often found in biological & biochemistry.

Monosubstituted Benzene

When among the location on the ring has actually been substituted with one more atom or team of atoms, the link is amonosubstituted benzene. If 2 positions are replaced, climate it"s a disubstituted, & for this reason on. Many of the monosubstituted compounds have their very own name and also some that the an ext common persons are detailed in the Table below:

Disubstituted Benzenes

When two of the location on the ring has actually been substituted with one more atom or team of atoms, the link is adisubstituted benzene. There is a different nomenclature to define the family member positions. Utilizing toluene as the example, the ortho orientation is the 1,2 relationship; the meta is1,3 and also the para is1,4. Note that there room two ortho and also meta positions, but only one para.

Where one group imparts a special name, surname the compound as a derivative of that molecule:
