(a)
Interpretation:
It is to be determined whether the two given molecules are constitutional isomers of each other.
Concept introduction:
The compounds having same molecular formula but different connectivity of the atoms are constitutional isomers. The arrangement of the atoms is different for constitutional isomers. From the total number of atoms and arrangement of atoms, it is decided that whether the two molecules are constitutional isomers or not.
Answer to Problem 4.16P
The two given molecules are not constitutional isomers of each other.
Explanation of Solution
The structures of the given molecules are
The molecular formula of the first compound is
The first molecule contains ten hydrogens, and the second molecule contains twelve hydrogens. However, the total number of hydrogens is different in each molecule. In case of constitutional isomers, the total number of atoms remains the same in the molecular formula. So both molecules are not constitutional isomers of each other.
The constitutional isomers are determined from the molecular formula and connectivity of the atoms.
