Constitutional isomers IUPAC names

Alkanes are a class of saturated hydrocarbons with the general formula C H2n. -2- They contain no functional groups, are relatively inert, and can be either straight-chain (normal) or branched. Alkanes are named by a series of IUPAC rules of nomenclature. Compounds that have the same chemical formula but different structures are called isomers. More specifically, compounds such as butane and isobutane, which differ in their connections between atoms, are called constitutional isomers. 

From among the 18 constitutional isomers of C8H18, write structural formulas, and give the IUPAC names for those that are named as derivatives of... 

A-12. Draw the constitutional isomers of C7H16 that have five carbons in their longest chain, and give an IUPAC name for each of them. 

For each molecular formula, draw all the possible constitutional isomers of alcohols with that formula. Give the IUPAC name for each alcohol. 

In essence, constitutional isomers will always have different International Union of Pure and Applied Chemistry (lUPAC) names (http //www.chem.qmw.ac.uk/iupac/), whereas stereoisomers must be identified by an additional nomenclature term. Some overlap exists between configurational isomers and conformational isomers. Configurational isomers are stable under nonnal conditions whereas interconversion of conformational isomers is often rapid at room temperature. The configurations of biomacromolecules are fixed by covalent bonding. However, the conformations are highly variable and dependent on a number of factors, including the interactions between atoms in the molecule and between the molecule and its environment. The term conformation is generally used to denote secondary and tertiary structures of biomacromolecules. 

Problem 4.13 Give the iUPAC name for each of the five constitutional isomers of molecular formula C6H14 in Problem 4.5.
