3-ethyl-3,4-dimethylnonane
Answer (2)
The name '3-ethyl-3,4-dimethyl nonane' refers to an organic compound, specifically an alkane, which is a type of hydrocarbon. Let’s break down the name to understand the structure of the compound:
Nonane : This indicates that the main carbon chain of the compound has 9 carbon atoms. The prefix 'non-' refers to nine carbon atoms, and '-ane' suggests that it is an alkane, meaning all carbon-carbon bonds are single bonds.
3-Ethyl : The 'ethyl' group is a substituent that consists of a 2-carbon chain (C2H5), and the '3-' means that this ethyl group is attached to the third carbon atom of the main nonane chain.
3,4-Dimethyl : The 'dimethyl' indicates that there are two methyl groups attached as substituents on the main carbon chain. The prefix 'di-' means there are two such groups. The numbers '3' and '4' specify that one methyl group is attached to the third carbon, and the other is attached to the fourth carbon of the nonane chain.
To visualize the structure:
Start by drawing a straight chain of 9 carbon atoms representing nonane.
Number these carbon atoms from 1 to 9.
Attach an ethyl group (CH2-CH3) to the 3rd carbon.
Attach a methyl group (CH3) to both the 3rd and 4th carbons.
Naming compounds in this way follows International Union of Pure and Applied Chemistry (IUPAC) nomenclature rules, which help provide a clear and standardized method for naming complex organic molecules. Understanding the structure from the name involves identifying the longest carbon chain, numbering it from the end nearest a substituent, and using the positioning numbers to signify the location of substituents on this chain.
3-ethyl-3,4-dimethylnonane is an organic alkane with a main carbon chain of 9 carbons. It features an ethyl group attached to the 3rd carbon and two methyl groups on the 3rd and 4th carbons. The structure follows IUPAC naming conventions for organic compounds.
