Q.29. - Organic Chemistry

Question

Question: a. Draw the 14 constitutional isomers of molecular formula ${\mathit{C}}_{\mathbf{8}}{\mathit{H}}_{\mathbf{9}}\mathit{C}\mathit{l}$  that contain a benzene ring.

b. Name all compounds that contain a trisubstituted benzene ring.

c. For which compound(s) are stereoisomers possible? Draw all possible stereoisomers.

Step-by-Step Solution

Answer

Answer

Step 1: Constitutional Isomers

The isomers which have the same molecular formula but different structures are called constitutional isomers. Such isomers consist of the same number of atoms of every element but differ from each other only in terms of bonding.

The constitutional isomers also have different IUPAC names.

Step 2: The constitutional isomers with molecular formula C 8 H 9 C l

a. The 14 constitutional isomers with molecular formula $C_8{H}_{9}Cl$  that contain benzene ring are as follows:

b. The names of the compounds which contain trisubstituted benzene are as follows:

c. The following two stereoisomers that are possible for the compound, 1-chloro-1-phenyl ethane are shown below:
