Conversation

Have you ever heard of an epoxide?

I think I came across it in my chemistry class, but I can't remember much about it.

It's actually a really interesting compound used in making plastics.

Oh, that makes sense! I should look into it more.

Root Explanation

Epoxide is formed from "epi-" (meaning upon or over) and "oxide" (from the Greek "oxys", meaning sharp or acid, and "-ide", a suffix used in chemistry to denote a binary compound). The term refers to a cyclic ether with an oxygen atom in a three-membered ring, indicating a compound that has an oxygen atom upon or over a carbon framework.

Memory Tip

Think of 'epi-' meaning 'upon' and 'oxide' relating to a compound with oxygen — this helps you remember that an epoxide is a compound with an oxygen atom in a special position.
