Nitrous acid is considered as a factomaric mixture of two forms. Write its structures. 

Racemnic mixture is formed by mixing two

What is the monomer of polyactic acid ? Give its structure.

Oxalic acid reacts with concentrated H_(2)SO_(4) to give a mixture of two gases. When this mixture is passed through caustic potash, one of the gases is absorbed. What is the product formed by the absorbed gas with caustic potash?

The necessary condition for a molecule to exhibit optical isomerism is dissymmetry or chiral. Thus all organic compounds which contain one as symetric carbon atom are chiral and exist in two stereoisomers. Although the two forms have the same structure, they have different arrangements of groups about the as symmetric carbon. In fact, they represent as symetric molecules. They do not have a plane of symmetry. They are related to each other as an object to its mirror image and are non superimposable. The two structures actually stand for dextro or (+) and leavo or (-) isomers. Since they are related each other as mirror images, they are commonly called enantiomers. Consider the following structures A,B,C,D Which of the following statements is not correct

Which is not formed by the physical mixture of two substances
