4 syllables: hy, dro, car, bon. Stress on car.
heye-droh-KAHR-buhn
/ˌhaɪdɹoʊˈkɑɹbən/
hydrocarbon is pronounced heye-droh-KAHR-buhn (/ˌhaɪdɹoʊˈkɑɹbən/). It has four syllables (hy-dro-car-bon), with the stress on "car". A hydrocarbon is a chemical compound composed exclusively of hydrogen and carbon atoms. They form the basis of many fuels and petrochemicals, with structures ranging from simple alkanes to complex aromatics. Hydrocarbons can be gases, liquids, or solids, and their properties depend on carbon chain length, bonding, and functional groups.

"Natural gas is primarily methane, a simple hydrocarbon used for heating and energy."
"Petroleum engineers refine crude oil to separate various hydrocarbon fractions for fuels and plastics."
"Aromatic hydrocarbons, like benzene, have ring structures that influence their chemical behavior."
Hydrocarbon is pronounced as /ˌhaɪ.droˈkɑːr.bən/ (US) or /ˌhaɪ.drəˈkɑː.bən/ (UK/AU). The primary stress falls on the third syllable: hydroCARbon. Begin with a light, high-front vowel in 'hy', then a centered 'dro' cluster, then a strong 'car' with the /ɑː/ vowel, ending with the schwa + n sound. A quick audio example is available in standard dictionaries or Forvo: search 'hydrocarbon pronunciation'.
Common errors include saying 'hy-dro-carb-on' with misplacement of stress and mispronouncing the 'car' as /kər/ or /kar/ without proper length. Another error is merging syllables too quickly so the 'dro' feels swallowed, and pronouncing the final 'bən' as 'bin'. Correction: keep the primary stress on the third syllable, clearly articulate /ˈkɑːr/ with a long vowel, and finish with a clear /ən/ (schwa-n).
US tends to retain a distinct /ˈhaɪ.droˌkɑr.bən/ with a rhotic /r/ in 'car'. UK and AU often have a non-rhotic influence on the final syllable but still maintain /ˈkɑː/ or /kɑː/ in 'car' and a clearer /ə/ in the final schwa. The main difference is rhoticity and the vowel quality of /ɑː/ vs /ɒ/ depending on local variants; US uses /kɑr/ while UK often uses /kɑː/ in non-rhotic contexts.
The difficulty comes from the three-consonant cluster around 'd' 'r' and 'c' in rapid speech, plus the long /ɑː/ in the 'car' syllable and the unstressed final /ən/. The sequence /droˈkɑː/ requires careful vowel length and a clear D-R transition; the final /bən/ has a soft 'b' followed by a schwa. Practice with slow articulation to separate syllables before linking them.
A key feature is the strong secondary stress pattern in longer compound words: hydroCARbon has primary stress on CAR, with less emphasis on HYDRO- and -bon. Ensure you keep the 'car' vowel long and not reduced, and avoid turning /ˈkɑːr/ into a short /kɔr/ in non-native speakers. Practicing the sequence with minimal pairs helps hear the difference.

Hydrocarbon comes from the combination of the Greek words hydro- meaning water (though in this sense it conveys a primitive sense of fuel-like composition rather than actual water chemistry) and carban or carbon, from Latin carbo for coal or charcoal. The term was adopted in the 19th century during the rapid expansion of organic chemistry as scientists distinguished compounds composed solely of hydrogen and carbon from other organic molecules containing additional heteroatoms. Early chemists identified simple hydrocarbons like methane and ethane and gradually categorized them based on saturation (alkanes, alkenes, alkynes) and ring structures (cycloalkanes, aromatics). First known uses appear in the literature of the mid to late 1800s as industrial chemistry matured, particularly with the advent of coal gas and petroleum refining. Since then, the vocabulary deepened to cover benzene, toluene, and larger polycyclic aromatic hydrocarbons, reflecting evolving models of bonding and hybridization in carbon frameworks. Today, hydrocarbons are foundational to fuels, plastics, and petrochemicals, with nomenclature that mirrors structural features such as chain length, branching, and ring systems.
