Start here

This is called the Dark L vs Light L, a hallmark of natural-sounding American speech. It comes out as KEH·muh·kuhl. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "The chemical weapon test was meant to be secret" or "The periodic table lists all known chemical elements" — more examples below.

Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.
01
Treating every L the same.
The L in "chemical" is a dark L — the back of the tongue rises toward the soft palate, adding a small "uh" quality before the L. Dark L adds a small schwa-like "uh" before the L. The back of the tongue lifts toward the soft palate.
chemical→KEH·muh·kuhl
02
Stressing the wrong syllable.
Stress falls on the first syllable, not the others. Stretch KEH — keep everything else short and quick.
keh·MUH·KUHL→KEH·muh·kuhl
03
Pronouncing the unstressed syllable too fully.
Don't pronounce the first syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
KEH·MUH·kuhl→KEH·muh·kuhl
Questions
Questions people ask about this.
How is "chemical" stressed in American English?
Stress falls on the first syllable — say "KEH" with a longer, fuller vowel and keep every other syllable short and quick. The respell "KEH-muh-kuhl" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
Why does the second syllable in "chemical" reduce to "uh"?
Unstressed syllables in American English collapse toward a schwa — a lazy, neutral "uh" sound. The full vowel is what textbooks teach, but in actual American speech every unstressed vowel reduces. The respell "KEH-muh-kuhl" shows the reduced form so you can hear the casual rhythm directly.
Is the American pronunciation of "chemical" different from British English?
American English uses different vowel shapes, a relaxed retroflex R, and connected-speech tricks like flap-T and glottal-stop T that British Received Pronunciation generally avoids. The respell "KEH-muh-kuhl" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
