Conversation

I was reading about different chemical groups, and I came across something called methoxyl.

Oh really? What does that do?

It’s a radical that’s similar to hydroxyl, apparently.

That’s interesting! Chemistry can be so complex sometimes.

Root Explanation

Methoxyl is formed from "meth-" (derived from the Greek word 'methy', meaning wine or alcohol) and "-oxyl" (from the Greek 'oxys', meaning sharp or acid). The term refers to a functional group in organic chemistry that includes a methoxy group, which is a methyl group attached to an oxygen atom.

Memory Tip

Think of 'meth-' relating to alcohol and 'oxyl' indicating something sharp or acidic, which helps you remember that methoxyl is a chemical group associated with alcohols.
