What is difference b/w Ball nd stick models, Fischer projections nd perspective formulas????
1 Answer
Well, perspective formulae, and Fischer projections are two-dimensional....
Explanation:
Whereas a ball and stick model is three-dimensional. And now let me speak like an old fogey. One failing of the modern chemistry student is his/her reluctance to use molecular models. These have always been allowed examination materials, and allows the student to vizualize and represent three-dimensional geometry. They seem to be under-utilized, and you can always tell that the student who will perform well in the organic test, is the one (or the few) who takes out a model, and has a fiddle with it.
There may be some people who can look at a Newmann or Fisher projection, and get a mind's eye model of molecular geometry. I am not one of them, and would always use a model to inform my reasoning. This is especially true for chiral structures.
