Interpretation:
The relation between the following Fischer Projection formulas should be determined and also whether they are identical molecules or enantiomers should be identified:
Concept Introduction:
Organic compounds are the compounds which are mainly composed C and H atoms. The branch of chemistry that deals with preparation, reactions, and properties of organic compounds is said to be
Constitutional isomers can be defined as the pair of molecules with the same molecular formula but different structural formula. Stereoisomers have same molecular and structural formula but they have different arrangement of atoms in the three-dimensional space.

Concept Introduction:
Organic compounds are the compounds which are mainly composed C and H atoms. The branch of chemistry that deals with preparation, reactions, and properties of organic compounds is said to be organic chemistry. The molecular formula of organic compound represents the number of bonded atoms with their atomic symbols. The structural formula represents all the bonded atoms with chemical bonds and the arrangement of atoms in the molecule. The compounds with same molecular formula and different structural formula are known as isomers. Isomers can be classified as constitutional isomers and stereoisomers.

Now consider the two bicyclic molecules A. and B. Note that A. is a dianion and B. is a neutral molecule. One of these molecules is a highly reactive compound first characterized in frozen noble gas matrices, that self-reacts rapidly at temperatures above liquid nitrogen temperature. The other compound was isolated at room temperature in the early 1960s, and is a stable ligand used in organometallic chemistry. Which molecule is the more stable molecule, and why?arrow_forward
