Hello, I'm always confused regarding naming of "Iso" and "sec", "tert" prefixes. I could say, a carbon is attached to two other carbons that carbon is called secondary carbon and same way tertiary. when it comes to "iso" how to identify and apply this prefix. What is the point out there? where we have to observe(carbon chain) you could kindly explain.

regards & thanks.

That "sciencegeek" page has quite a few 1-methyl nomenclature errors...
