Hint: The isomers which have the same molecular or chemical formula but contain different structures are known as structural isomers. Structural isomers are also called constitutional isomers. The number of possible structural isomers is going to depend on the number of carbons in it.
Complete answer:
- In the question it is asked about the structural isomers which are formed by .
- The molecular formula of the given compound is .
- The possible structural isomers with the molecular of are as follows.
- Means by seeing above possible structural isomers we can say that these four structural isomers are going to form with the molecular formula .
- In the above structures propylamine is an example for primary amine.
- Ethyl methyl amine is an example for secondary amine.
- In isopropyl amine also the amine is primary amine.
- In trimethylamine the amine is tertiary in nature.
- Tertiary amines are more basic in nature when compared to primary and secondary due to the presence of +I effect caused by the three methyl groups in trimethylamine.
- Therefore there are four structural isomers that are going to be possible with the molecular formula of .
Note:
If there is an absence of a plane of symmetry and non-superimposable structures in the amines then we can call them that they are having chiral carbons in it. With the structural formula by using we cannot form any chiral compound.
