Common Prefix

What do the terms "neo" and "iso" tell us regarding the structure of the molecule?

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 neo- refers to a substituent whose second-to-last carbon of the chain is trisubstituted (has three methyl groups attached to it).

Is this what you meant when you asked about the structure of the molecule?
