I just read about aliphatic compounds in my chemistry book.

Oh really? What makes them different from other compounds?

They have carbon atoms linked in open chains, which is pretty interesting.

That does sound cool! I didn't know that about aliphatic compounds.

Root Explanation

Aliphatic is formed from "aliphaticus" (from Greek "aleiphar" meaning to anoint or oil) and the suffix "-ic" (meaning pertaining to). The term refers to organic compounds that are structured in open chains, resembling oils or fats, hence the connection to the meaning of oil.

Memory Tip

Think of the Greek word for oil ('aleiphar') to remember that 'aliphatic' refers to compounds that are like oils or fats.
