How to Write 腙 (zōng) — Meaning “Hydrazone”

Imagine a "zoo" (sounds like zōng) where the animals are made of "meat" (月). The animals hold hands in a chain, representing the nitrogen bonds in hydrazones. This visual links the sound and meaning to the character.

The left radical 月 must be written narrow, with two horizontal strokes inside, not three. The right half 宗 has an upper part 宀 that sits above 示, but note the bottom of 宗 has a small horizontal stroke before the two dots. Keep the character balanced left-to-right.

腙 has the 月 radical, but 朔 (shuò, "new moon") has 月 on the left with 屰 on the right, meaning the moon's phase. 朕 (zhèn, "I" in ancient China) has 月 on the left and 关 on the right, and is a royal pronoun. 腙 is a chemistry term, while 朔 and 朕 are everyday words.

腙 is a technical term only found in chemistry, referring to hydrazone compounds. It appears in academic papers, pharmaceutical research, and organic chemistry textbooks. You won't encounter it in daily conversation or general reading.

Common words containing 腙 include: 腙类 (zōng lèi) — hydrazones; 苯腙 (běn zōng) — Phenylhydrazone; 缩腙 (suō zōng) — Semicarbazone.
