Concept introduction:
Constitutional isomers are having the same molecular formula and different bond connectivity between the atoms.
Answer to Problem 1P
The numbers of constitutional isomers of molecular formula
Explanation of Solution
The given molecular formula is
Therefore,
There will be five alcohol isomers (due to four carbons) and two ether isomers.
Hence,
