Chapter 3, Problem 66IP

Interpretation Introduction

Interpretation:

Constitutional isomers are needed to be found for the given molecular formula ${\text{C}}_{\text{3}}{\text{H}}_{\text{8}}\text{O}$ and have to give the most acidity order for the isomers.

Concept introduction:

Constitutional isomers:

• Constitutional isomers are isomers which have the same molecular formula and different bond connectivity between the atoms in the molecule.

Acidic strength of the molecule depends on the stability of the Conjugate anion.

• If the conjugate anion is more resonance stabilized, the acid considered as strong acid and the anion is weak base.
• If more sterically hindered the group, acidic nature is less. That means bulkiness decreases the acidic strength of the molecule. 

To draw: The all possible constitutional isomers for the molecular formula ${\text{C}}_{\text{3}}{\text{H}}_{\text{8}}\text{O}$
