Find a English O Chem textbook which has been translated into your mother language. Then read this two version (English and translated version) at the same time.

First, read the post at the top of the Forum ('FORUM RULES: READ THIS BEFORE POSTING!') about writing the topic of your question in the title. Then:

Get a very low level chemistry book in English, i.e. high school level or first year general chemistry. Your English level seems high enough to be able to read something like that.

Then you have to read it together with your dictionary — don't look up every word and try to read it once without your dictionary first. It will take a lot of time at first, but it gets easier as you go on. Depending on your level, and what kind of studying you are already doing, it will be a good idea to keep notes of words that often come up. The best way to improve your vocabulary is by constant reading. Low level books are best because they're easy to read. Simply reading a translation of a high-level text is not so useful as they often contain too many rare words. As your vocabulary increases, step up to higher level texts. When reading published articles, just remember that they are often difficult for native speakers to read as well.

Don't worry too much about words you don't understand. Remember that many words in organic chemistry are new to the native speakers too. If you think a word is very common, such as 'solvent', it's good to look it up. If a word is not so common, such as 'enantioselective', then you don't need to look it up, just learn it as a new word by itself.
