A structural formula is a graphical representation of the atoms and bonds in a molecule. It shows the arrangement of atoms and the connections between them.
To draw a structural formula, first identify the atoms present in the molecule and their respective numbers. Then, draw the atoms and connect them with lines to represent the bonds between them. Remember to adhere to the valence rules of each atom.
Absolute configuration refers to the spatial arrangement of atoms in a chiral molecule. It is determined by the sequence of atomic numbers of the atoms attached to the chiral center.
The absolute configuration of a molecule can be determined by using the Cahn-Ingold-Prelog (CIP) rules. These rules assign priorities to the atoms attached to the chiral center based on their atomic numbers and then determine the configuration based on the direction of the lowest priority group.
The structural configuration only shows the arrangement of atoms and bonds in a molecule, while the absolute configuration takes into account the spatial arrangement of atoms in a chiral molecule. Structural configuration can be easily determined through visual representation, while absolute configuration requires the use of CIP rules.
