Q.37. - Organic Chemistry

Question

Question: Draw the structure of all compounds that fit the following descriptions. a. Five constitutional isomers having the molecular formula ${\mathit{C}}_{\mathbf{4}}{\mathit{H}}_{\mathbf{8}}$ b. Nine constitutional isomers having the molecular formula ${\mathit{C}}_{\mathbf{7}}{\mathit{H}}_{\mathbf{16}}$ c. Twelve constitutional isomers having the molecular formula ${\mathit{C}}_{\mathbf{6}}{\mathit{H}}_{\mathbf{12}}$  and containing one ring

Step-by-Step Solution

Answer

Answer

a.

Constitutional isomers of  $C_4{H}_8$

b.

Constitutional isomers of  $C_7{H}_{16}$

c.

Constitutional isomers of  $C_6{H}_{12}$

Step 1: Constitutional isomers

The constitutional isomers are obtained by the different arrangements of the groups of atoms. The molecular formula for all the different structures is the same, but the properties are different.

Step 2: Explanation

a.

 

The constitutional isomers of $C_4{H}_8$ have four carbon atoms and eight hydrogen atoms, but the orientation of the groups is different around the bonds.

Constitutional isomers of  $C_4{H}_8$

 

b.

 

The constitutional isomers of  $C_7{H}_{16}$ have seven carbon atoms and $16$ hydrogen atoms as follows:

Constitutional isomers of  $C_7{H}_{16}$

 

c. The constitutional isomers of  $C_6{H}_{12}$ having six carbon atoms and 12 hydrogen atoms are as follows:

Constitutional isomers of  $C_6{H}_{12}$
