How to remember 酮
酮 combines 酉 (yǒu), a wine jar that marks chemical and fermentation words, with 同 (tóng), which gives the sound. Picture a lab jar holding the same (同) kind of chemical each time: a ketone.
酮 is a technical chemistry term and mostly appears in compound words like 丙酮 (bǐngtóng, acetone) and 酮体 (tóngtǐ, ketone bodies). You will see it in science textbooks, medical reports, and product labels. Example: 指甲油去除剂里有丙酮。(Zhǐjiayóu qùchújì lǐ yǒu bǐngtóng.) Nail polish remover contains acetone.
Common mistake: Learners sometimes confuse 酮 with 铜 (tóng, copper), since both share 同 and the same pronunciation. Remember that 酉 points to chemical compounds, while 钅 points to metals.
