Hello all, me and my lecture partner need help understanding why the pink answers are correct, we've tried to reason them out but with no luck

So I'm completing my last homework for my college Ochem class and wanted to know if these were right , I'm also looking for why their wrong if their wrong because I genuinely need to know the material and sometimes I just don't know where I got off track.
