What does ISO mean when naming organic compounds?

IUPAC name: 1-pentanol. 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. Common name: isopentane.

Is ISO included in naming?

the prefixes iso- and cyclo- are included (note they are are used without hyphens and are part of the substituent name)

What are the rules for naming organic compounds?

Compound Naming Steps

• Step 1: Locate the longest carbon chain in our compound.
• Step 2: Name that longest carbon chain.
• Step 3: Figure out what the ending (suffix) should be.
• Step 4: Number your carbon atoms.
• Step 5: Name the side groups.
• Step 6: Put the side groups in alphabetical order.

What does ISO and neo mean in organic chemistry?

The key difference between iso and neo structures is that the prefix iso refers to an organic compound containing all carbon atoms except one forming a continuous chain whereas the prefix neo refers to an organic compound containing all carbon atoms except two forming a continuous chain.

What does ISO mean in science?

Scientific definitions for iso (2 of 2) A prefix that means “equal,” as in isometric, “having equal measurements.” A prefix used to indicate an isomer of an organic compound, especially a branched isomer of a compound that normally consists of a straight chain.

Why are rules important to naming organic compounds?

The primary function of chemical nomenclature is to ensure that a spoken or written chemical name leaves no ambiguity concerning which chemical compound the name refers to: each chemical name should refer to a single substance. The form of nomenclature used depends on the audience to which it is addressed.
