Copper(II) sulfate, also known as cupric sulfate, is an inorganic compound with the chemical formula CuSO₄. It is a blue crystalline solid that is soluble in water. Copper(II) sulfate is used as a fungicide, as an ingredient in fertilizers, and as a mordant in dyeing. It is also used in the production of other copper compounds, such as copper(II) oxide and copper(II) chloride.
The Chemical Abstracts Service (CAS) Systematic Nomenclature
When it comes to naming chemical compounds, the Chemical Abstracts Service (CAS) is the go-to authority. Their systematic nomenclature system provides a standardized way to assign unique names to all chemical substances, ensuring that scientists around the world can communicate about them clearly and consistently.
The Basic Structure of a CAS Systematic Name
A CAS systematic name consists of three main parts: the parent name, the prefixes, and the suffixes.
- Parent name: This is the name of the core structure of the compound. It is based on the number of carbons in the chain. For example, pentane is the parent name for a compound with five carbons in its chain.
- Prefixes: Prefixes are added to the parent name to indicate the presence of substituent groups (e.g., methyl, ethyl, etc.). They are arranged alphabetically. For example, 2-methylpentane is the name for a compound with five carbons in its chain and a methyl group attached to the second carbon.
- Suffixes: Suffixes are added to the end of the parent name to indicate the presence of functional groups (e.g., -ene, -one, etc.). They are arranged in order of priority. For example, 2-methyl-1-pentene is the name for a compound with five carbons in its chain, a methyl group attached to the second carbon, and a double bond between the first and second carbons.
Additional Rules
In addition to the basic structure, there are a number of additional rules that govern the formation of CAS systematic names. These rules cover such things as the order of precedence for prefixes and suffixes, the use of hyphens and commas, and the treatment of special cases (e.g., branched chains).
The Importance of CAS Systematic Names
CAS systematic names are an essential tool for scientists because they provide a clear and concise way to identify and classify chemical compounds. They are used in a wide variety of applications, including:
- Chemical literature searching
- Chemical databases
- Chemical safety assessments
- Patent applications
Helpful Table
The following table summarizes the key elements of a CAS systematic name:
| Element | Description |
|---|---|
| Parent name | The name of the core structure of the compound |
| Prefixes | Indicate the presence of substituent groups |
| Suffixes | Indicate the presence of functional groups |
| Order of precedence | Prefixes and suffixes are arranged in order of priority |
| Use of hyphens and commas | Hyphens are used to separate prefixes; commas are used to separate suffixes |
| Special cases | There are special rules for naming branched chains and other special cases |
Question 1: What is the systematic name of cui?
Answer: The systematic name of cui is 2,3,4-trimethyl-6-phenyl-1-heptanol.
Question 2: What are the structural features of cui?
Answer: Cui is a branched-chain alcohol with a phenyl group attached to carbon 6. It has a total of seven carbon atoms, three of which are methyl groups.
Question 3: How is cui synthesized?
Answer: Cui can be synthesized by the reaction of 2,3,4-trimethyl-6-phenyl-1-hexanone with sodium borohydride in methanol.
