Question

Draw the structural formulas for two constitutional/structural isomers for a compount having a molecular formula of C₄H5.

Answer 1

Since, C₄H₅^. is a radical compound. The compounds having same molecular formula but different structural formula known as the constitutional or structural isomers. All possible constitutional or structural isomers C₄H₅^. Radical are given as below:-

(1) The possible structure of C₄H₅^. Radical is given as below:-

(2) The possible structure of C₄H₅^. Radical is given as below:-

(3) The possible structure of C₄H₅^. Radical is given as below:-

So, from the above structures (1), (2) and (3) it is clear that, all the above structures have the same molecular formula (C₄H₅^. Radical) but different structural formula, which are known as the constitutional or structural isomers.
