Interpretation:
The structural formulas for the constitutionally isomeric alcohols of molecular formula
Concept Introduction:
Isomers that have the same molecular formula but differ in the way in which different atoms are connected are known as constitutional isomers.
The number of atoms of each element present in the compound, is known as the molecular formula.
