The pronunciation of chemical words,
Formulae and equations
The modern trends are:
1. The accenting of names of chemical substances on the final syllable is notrecommended where the accent is not emphatic (such as the names amine [´æmaɪn], sulphide [´sʌlfaɪd], amidin [´æmɪdɪn]).
2. The general trend of the accent in the English language is now to be away from the end and toward the beginning of the word.


3. The ending ide should be pronounced as [aɪd] (bromide [´broumaɪd], chloride [´klɔ:raɪd], oxide [´ɔksaɪd]).
4. For chemical names ending in ine, the tendency is now to pronounce [i:n] (chlorine [´klɔ:ri:n], iodine [´aɪədi:n]).
This conflicts in sound with the pronunciation of the ending ene but this is only with a few words, as benzine and benzene [´benzi:n], fluorine and fluorene [´fluəri:n], glycerin [ɡlɪsə´ri:n].
5. The ending yl should be pronounced [ɪl] (methyl [´meθɪl]).
6. The ending ile should be pronounced [ɪl] (nitrile [´naɪtrɪl]).
7. Adjectives ending in ic should be accented on the next to the last syllable, as glyceric [ɡlɪ´serɪk].
8. Words ending in valent [´veɪlənt] should be pronounced as trivalent [´traɪˌveɪlənt], monovalent [´mɔnouˌveɪlənt], divalent [´daɪˌveɪlənt] or bivalent [´baɪˌveɪlənt].
