I have done CHM1051 & CHM1052, which are the advanced version of CHM1011 & CHM1022.
CHM1011 is about physical chemistry, whereas CHM1022 is about organic and inorganic chemistry. At first year level, they are not linked together whatsoever. You don't need any knowledge from CHM1011 in order to do well in CHM1022. The only thing that completing CHM1011 might be beneficial is that you will be more familiar with the whole lab thing.
Also, none of the topics in CHM1022 goes in much detail so yeah, if you put in a little bit of effort, a HD is pretty easy to get. Definitely go for it!
(I stopped going to lectures after Week 4, not that it's not useful, I just found it really boring and I just couldn't focus. I crammed the whole course in SWOTVAC by watching all the lectures on MULO in 5 days and doing past exams, and I still managed to get a 94.)
