What are some common mistakes students make when converting Fischer Projections to Bond Line Views?
Just to retire this question....
...the one fatal mistake you can make is NOT to make a model. There may be some people who can look at a perspective formula on the written page, and translate this to three-dimensional geometry in their mind's-eye. I am not one of them, and would ALWAYS make a model to inform my reasoning and my sense of geometry. And distinguished professors of inorganic and organic chemistry would ALWAYS have models of their target molecules on their desks.
And I add that molecular models are always permitted examination materials.
