How do you name a compound with multiple substituents?
When two or more identical substituents are present in a molecule, a numerical prefix (di, tri, tetra etc.) is used to designate their number. However, each substituent must be given an identifying location number. Thus, the above compound is correctly named: 3,3-dimethylpentane.
How do you name compounds with multiple functional groups in them?
If the compound includes more than one functional group, the one with the highest priority is the “parent structure” and determines the “parent name”; the other groups will be regarded as “substituents”. The “suffix” is used to indicate the name of the parent structure, and the “prefix” is for the substituent.
How do you name organic compounds with double and triple bonds?
Higher alkenes and alkynes are named by counting the number of carbons in the longest continuous chain that includes the double or triple bond and appending an -ene (alkene) or -yne (alkyne) suffix to the stem name of the unbranched alkane having that number of carbons.
How do you name complex aromatic compounds?
In general, to name an aromatic compound, you can follow these steps:
- Identify and name the parent.
- Identify and name the substituents.
- Number the ring to give the substituents the smallest possible number.
- Put the substituents alphabetically followed by the parent name.
How many monosubstituted derivatives of benzene are possible?
Benzene can form only one type of monosubstituted means that it cannot form different atoms just by replacing the position of attached atom like in ortho, para or meta position which occurs when two atoms are attached to it. Hence it forms only one type of monosubstituted product.
What is benzenes common name?

What is use to indicate substituents on a benzene ring?
In some cases, the benzene ring needs to be treated as a substituent. In these cases, the term phenyl, is used to designate the presence of C6H5- as a substituent. The method should be used when the benzene ring is a substituent of the root (the root contains the principle functional group).
Can a compound have multiple functional groups?
A single compound often contains several functional groups. The six-carbon sugar molecules glucose and fructose, for example, contain aldehyde and ketone groups, respectively, and both contain five alcohol groups (a compound with several alcohol groups is often referred to as a ‘polyol’).
How do you name alkynes with two triple bonds?
When there are two triple bonds in the molecule, find the longest carbon chain including both the triple bonds. Number the longest chain starting at the end closest to the triple bond that appears first. The suffix that would be used to name this molecule would be –diyne.
How do you name organic compounds with multiple functional groups?
In naming molecules containing one or more of the functional groups in Group A, the group of highest priority is indicated by suffix; the others are indicated by prefix, with priority equivalent to any other substituents.
