Q. 12.3 - An Introduction to General, Organic, and Biological Chemistry

Question

Draw the condensed structural formula, or line-angle formula if cyclic, for each of the following: 

a. propyl alcohol 

b. 3-pentanethiol 

c.2-methyl -2-butanol 

d. 4-bromophenol

Step-by-Step Solution

Answer

(a) The structure of the compound is${\mathrm{CH}}_3-{\mathrm{CH}}_2-{\mathrm{CH}}_2-\mathrm{OH}$.

(b) The structure of the compound is${\mathrm{CH}}_3-{\mathrm{CH}}_2-\mathrm{CH}(\mathrm{S}-\mathrm{H})-{\mathrm{CH}}_2-{\mathrm{CH}}_3$.

(c) The structure of the compound is${\mathrm{CH}}_3-\mathrm{C}\left({\mathrm{CH}}_3\right)\left(\mathrm{OH}\right)-{\mathrm{CH}}_2-{\mathrm{CH}}_3$.

(d) The structure of the compound is 

Part (a) Step 1: Given Information

We are given the name of the compound and we have to find the structure of the compound.

Part (a) Step 2: Explanation

The name of the compound is propyl alcohol, and it contains propane and alcohol,

which gives the structure ${\mathrm{CH}}_3-{\mathrm{CH}}_2-{\mathrm{CH}}_2-\mathrm{OH}$.

Part (b) Step 1: Given Information

We are given the name of the compound and we have to find the structure of the compound.

Part (b) Step 2: Explanation

The name of the compound is$3$- pentane thiol , and it contains pentane and thiol,

which gives the structure${\mathrm{CH}}_3-{\mathrm{CH}}_2-\mathrm{CH}(\mathrm{S}-\mathrm{H})-{\mathrm{CH}}_2-{\mathrm{CH}}_3$.

Part (c) Step 1: Given Information

We are given the compound structure and we have to find out the IUPAC name of the compound.

Part (c) Step 2: Explanation

The compound contains C carbon, H hydrogen, and O oxygen with one chain and two branches of methyl and alcohol, so the name of the compound is$2$-methyl-$2$-butanol .

Hence, the structure of the compound is${\mathrm{CH}}_3-\mathrm{C}\left({\mathrm{CH}}_3\right)\left(\mathrm{OH}\right)-{\mathrm{CH}}_2-{\mathrm{CH}}_3$.

Part (d) Step 1: Given Information

We are given the compound structure and we have to find out the IUPAC name of the compound.

Part (d) Step 2: Explanation

The compound contains C carbon, H hydrogen, and O oxygen with one ring and two branching of ethyl and alcohol, so the structure is
