Q. 11.46 - An Introduction to General, Organic, and Biological Chemistry

Question

Convert each of the following line-angle formulas to a condensed structural formula and give its IUPAC name: ($11.3$)

a. 

b.

Step-by-Step Solution

Answer

(a) The required condensed structural formula is ${\mathrm{CH}}_3-{\mathrm{CH}}_2-{\mathrm{CH}}_2-\mathrm{CH}\left({\mathrm{CH}}_3\right)-{\mathrm{CH}}_2-{\mathrm{CH}}_2-{\mathrm{CH}}_3$  and IUPAC name is $4-Methylhep\tan e$

(b) The required condensed structural formula is ${\mathrm{CH}}_3-\mathrm{CH}\left(\mathrm{Cl}\right)-\mathrm{CH}\left({\mathrm{CH}}_3\right)-\mathrm{CH}\left(\mathrm{Br}\right)-{\mathrm{CH}}_2-{\mathrm{CH}}_3$ and the IUPAC name is $4-bromo-2-chloro-3-methylhexane$

Part (a) Step 1: Given information

We need to find the condensed formula and IUPAC name of the given line angle formulas i.e. 

Part (a) Step 2: Explanation

We know that

The Condensed structural formula represents each element's symbol and the bond between each element 

Therefore, The required condensed structural formula is

 ${\mathrm{CH}}_3-{\mathrm{CH}}_2-{\mathrm{CH}}_2-\mathrm{CH}\left({\mathrm{CH}}_3\right)-{\mathrm{CH}}_2-{\mathrm{CH}}_2-{\mathrm{CH}}_3$

And IUPAC name is the name that is accepted worldwide.

So, The IUPAC name is $4-methylpen\tan e$

Part (b) Step 1: Given information

We need to find the condensed formula and IUPAC name of the given line angle formulas i.e.

Part (b) Step 2: Explanation

We know that

The Condensed structural formula represents each element's symbol and the bond between each element 

Therefore, The required condensed structural formula is

 ${\mathrm{CH}}_3-\mathrm{CH}\left(\mathrm{Cl}\right)-\mathrm{CH}\left({\mathrm{CH}}_3\right)-\mathrm{CH}\left(\mathrm{Br}\right)-{\mathrm{CH}}_2-{\mathrm{CH}}_3$

And IUPAC name is the name that is accepted worldwide.

So, The IUPAC name is $4-bromo-2-chloro-3-methylhexane$
