WebCarbon “b” is connected to one oxygen and one hydrogen. However, because of the double bond, carbon “b” is treated as if it is connected to two oxygens. The same rule is applied for any other double or triple bond. So, when you see a double bond count it as two single bonds when you see a triple bond cut it as three single bonds. WebFischer projections are especially useful in d rawing carbohydrates since they contain multiple chiral centers which are more time-consuming to draw. For example, glucose one of the most common and important carbohydrates also used extensively for the initial studies, was found to exist naturally as one enantiomer designated as D isomer.

WebJul 19, 2024 · The wedge and dash model is based on valence shell electron pair repulsion (VSEPR). One of the central tenets of VSEPR theory is that when bonding occurs between atoms with lone pairs of electrons, they will be arranged so that these lone pairs lie along one axis.
