Get Naming Organic Compounds Practice

The term Iso in organic chemistry refers to an organic compound containing all carbon atoms except one form a continuous chain. The use of this prefix is to name a compound having a carbon chain containing one branch. The term Sec in organic chemistry refers to the attachment at a secondary carbon.

The prefix iso-, which stands for isomer, is commonly given to 2-methyl alkanes. In other words, if there is methyl group located on the second carbon of a carbon chain, we can use the prefix iso-. The prefix will be placed in front of the alkane name that indicates the total number of carbons.

IUPAC rules of organic nomenclature Step 1: Determining the primary functional group. ... Step 2: Determining the primary carbon chain. ... Step 3: Naming the primary carbon chain. ... Step 4: Numbering the primary carbon chain. ... Step 5: Indicating the position of the primary functional group. ... Step 6: Naming the substituents.

multiplier prefixes (di-, tri- tetra- etc.) are ignored. prefixes such as neo-, sec-, tert- (or their abbreviations) are ignored. the prefixes iso- and cyclo- are included (note they are are used without hyphens and are part of the substituent name)

The prefix "iso" is used when all carbons except one form a continuous chain. This one carbon is part of an isopropyl group at the end of the chain. "Iso" can also indicate that the molecule is an constitutional isomer of another molecule with a common (or trivial) name.

In summary, the name of the compound is written out with the substituents in alphabetical order followed by the base name (derived from the number of carbons in the parent chain). Commas are used between numbers and dashes are used between letters and numbers. There are no spaces in the name.

The only prefix which is used when putting the substituents in alphabetical order is iso as in isopropyl or isobutyl.
