Chapter 4.3, Problem 15ATS

Interpretation Introduction

Interpretation:

Constitutional Isomers of heptane have to be drawn.

Concept Introduction:

Isomers: Compounds that have same molecular formula but different structural formula.

Constitutional isomers: Compounds that have same molecular formula but different connectivity (arrangement of atoms are different).

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.
• 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.
