Answer to draw the fischer projection for the monosaccharide drawn as a haworth projection below. How can we draw fischer projections for one-five carbon compounds for example, say we have pentane-2,3,4-triol ($\ce{ch3-choh-choh-choh-ch3}$ image below) with wedge and dash structure, the alc. To draw a mirror image of a fischer projection, simply exchange the left and right positions, whilst keeping the top and bottom unchanged fischer projections are very useful to determine if a compound is chiral or achiral. In order that the fischer projection may be obtained, the longest continuous carbon chain must first of all be arranged in the overall eclipsed conformation.
