WebDec 20, 2024 · Add all of the bonds. Use the octet rule to determine the number and type of bonds present. Each atom’svalence shell should contain 8 electrons for the molecule to be stable. Some atoms may be double or triple bonded to achieve this. [3] In a water molecule, add a single bond from the oxygen to both hydrogens. WebMar 26, 2016 · Typically, you can only have diastereomers when the molecule has two or more chiral centers. The maximum number of possible stereoisomers that a molecule can have is a function of 2 n, where n is the number of chiral centers in the molecule. Therefore, a molecule with five chiral centers can have up to 2 5 or 32 possible stereoisomers!
