Q. 14.60 - An Introduction to General, Organic, and Biological Chemistry

Question

 Draw the condensed structural formulas for a and $\mathbf{b}$ and line angle formulas for $\mathrm{c}$and $\mathrm{d}$ :

a. pentyl formate

b. 5 -bromopentanoic acid

C. 3.5-dimethylhexanoic acid

d. butyl propanoate

Step-by-Step Solution

Answer

Part a)   pentyl formate  :

Part b)  5-bromopentanoic acid:

   

Part c)    3,5-dimethylhexanoic acid :

     

Part d)   butyl propanoate:

       

Step - 1 Given information (part-a)

The pentyl (five carbon atom) group replaces the -H  atom of the carboxylic acid in the name pentyl formate. 

Pentyl formate has a condensed structure.

Step - 2 Explanation (part-a)

Step -3 Given informationb (part-b)

The word pentancic acid denotes a structure with five carbon atoms, and 5 -bromo denotes the presence of a -Br group on the $5^{\text{th }}$carbon atom. The structural formula for 5 bromopentanoic acid in its condensed form is.

Step -4 Explanation (part-b)

Step - 5 Given information (part-c)

• Hexanoic acid denotes a structure with six carbon atoms, while 3,5-dimethyl denotes a structure with three carbon atoms. 
• The  and 5 th carbon atoms are connected to the $3^{\text{rd }}$  group. 3,5 dimethylhexanoic acid has the following line-angle formula:

Step - 6 Explanation (part- c)

Step -7 Given information (part -d)

Butyl propanoate is named after the butyl (four carbon atom) group that replaces the carboxylic acid's - H atom. 

Butyl propanoste's line-angle formula is:

Step - 8 Explanation (part- d)
