WebSince D-glucose is an aldohexose, it must possess four chiral carbon atoms and can exist in 2 4 = 16 stereoisomers (see Table I). In order to determine which of these isomers is actually D-glucose, a reference compound of known absolute configuration is needed, which can be prepared from, or converted to, D-glucose. Because the first ... WebSal says O has 2 lone pair of electrons which tend to form a bond with carbon. However, this O has completed its octet by sharing an electron with H and C (5) each, so it has 8 electrons and filled its octet. So why would it try to form a bond with the other carbon C (1)? • ( 4 votes) Ivana - Science trainee 4 years ago
