(The course of compounds, which consists of benzene or substituted derivative that 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.|
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:
|OTHER sensible GROUPS|
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:
|Toluene is the parent name||Aniline is the parent name||Benzoic mountain is the parental name||Benzaldehyde is the parent name|
If neither team imparts a distinct name, situate the groups & alphabetize.
If one team imparts a distinct name, surname the molecule as a derivative of that compound and also if no team imparts a special name, list castle in alphabet order, offering them the lowest set of numbers
|Toluene is the parent name||Aniline is the parent name||No distinct name|
