Interpretation Introduction

Interpretation:

Newman projection for the given compound and IUPAC name has to be provided.

Concept Introduction:

Nomenclature of organic compounds:

The naming of the organic compound is given by IUPAC (International Union for pure and applied chemistry). In the IUPAC names consist of certain rules for giving chemical names they are,

• The longer number of Carbon chain of a compound is identified this is called parent of the compound.
• In the cyclic compounds the number of carbon involving in ring formation is called parent of the compound.
• The compound have more than one parent chains means the larger number of substitutions present in the chain is consider as a parent chain.
• The names of all substituents are arranged by alphabets to starts with lowest numbering.
• The complex substituent is built by a substituent on a substituent; so called complex substituent.
• In the complex substituent having compounds the substituent name is assigned by a name each of them based on numbers going away from the parent.

Conformations: Rotation about C-C single bonds allows a compound to adopt a variety of possible three-dimensional shapes.

Newman projections: The new conformations of compounds can be drawn and analyzed by Newman projections. A Newman projection visualizes different conformations of Carbon-carbon chemical bond from front to back with the front carbon represented as a black dot and the back represented as a circle
