trichloro-comb. form

Stress is usually determined by a subsequent element and vowels may be reduced accordingly. If the subsequent element is an existing word, it is likely to retain its original stress pattern, e.g. trichlorophenol Brit.

/trʌɪˌklɔːrəʊˈfiːnɒl/, U.S.

/traɪˌklɔroʊˈfiˌnɔl/,

/traɪˌklɔroʊˈfiˌnɑl/.

Forms: before a vowel also trichlor-.

Etymology: < tri- comb. form 3c + chloro- comb. form².

Chemistry.

A formative analogous to tribromo- comb. form, expressing the substitution of three atoms of chlorine for hydrogen, as in trichlorobenzene, C₆H₃Cl₃; so trichloracetic acid, CCl₃.CO₂H, etc. Also triˌchlorocetˈaldehyde n. (also ˌtrichloracetˈaldehyde) = chloral n.
