Question

Which one of the following statements is not correct?
A) Fischer projection represents the molecule in an eclipsed conformation B) Newman projection can be represented in eclipsed, staggered and skew conformations C) Fischer projection of the molecule is its most stable conformation D) In Sawhorse projections, the lines are inclined at an angle of 120 deg to each other.

Answer 1

C)

because:

In Fischer projections, the convention is that the lines going up and down on a page are going away from you in space (into the desk below the page), and the lines going left and right are coming out toward you (as if to hug you). ... So too that in a Fischer projection, each chirality center is drawn individually.

C) Fischer projection of the molecule is its most stable conformation

 Explanation:

Fischer projections were originally proposed for the depiction of carbohydrates and used by chemists, particularly in organic chemistry and biochemistry.A Fischer projection always uses an eclipsed conformation. A Newman diagram can represent either an eclipsed conformation or a staggered conformation or a skew conformation.
