Kwright, I googled "Я ненавижу бизнеса" and got 2 results. One was your post, other was some king of deliberate nonsense. "Я ненавижу бизнес" gave 283 results. Probably you got confused with negative constructions, where Genitive is acceptable and even preferable: "Я вижу кирпич." - "Я не вижу кирпича."

IamMarat, look, I am afraid your post can only confuse foreigners. As a native speaker you have a natural feeling of language, but to point out what is correct and what is not, you need more literary practice and in-depth theoretical background. In your examples 1a may be correct with some context (for example, when you speak in fact about a bottle of water), 1b - see Partitive Case, 2a and 3a are correct and even preferable because of negation (see also Abessive Case). 4c is a set phrase (again with Abessive) rather than idiom, but 4a most probably will be recognized by experts as correct as well.
