Chapter 3: Q20 E-a (page 88)

Give IUPAC names for the following alkanes, and convert each drawing

into a skeletal structure.

Short Answer

Expert verified

(a) The IUPAC name of the structure is 3,3,5-Trimethylheptane.

Step by step solution

01

IUPAC name of alkanes

The parent hydrocarbon is identified in the beginning in the IUPAC nomenclature. The longest hydrocarbon chain is considered as the parent name.

02

IUPAC name and skeletal structure of compound a

(a)The longest chain of the given compound has six carbon atoms and is called heptane. The third carbon atom has two methyl groups and the fifth carbon atom has one methyl group. Hence, the IUPAC name of the compound is 3,3,5-Trimethylheptane.The skeletal structure can be given as:

Skeletal structure of compound a

In the next chapter we’ll look at cycloalkanes—saturated cyclic hydrocarbons—and we’ll see that the molecules generally adopt puckered, nonplanar conformations. Cyclohexane, for instance, has a puckered shape like a lounge chair rather than a flat shape. Why?

Construct a qualitative potential energy diagram for rotation about the C-C bond of 1,2-dibromo ethane. Which conformation would you expect to be most stable? Label the anti and gauche conformations of 1,2-dibromo ethane.
