Chemhelper is a very basic website specializing purely in organic chemistry. When first arriving at this website the simplicity is very clear, it makes navigating the website extremely easy.
However, the main focus of their content seems to be purely directed towards students. The wiki may be somewhat useful even if it is rather small.
After navigating through this website it is clear that it is rather new but even though that is the case it may still be a useful tool to check out.
