Interpretation Introduction

Interpretation:

Constitutional isomers are to be found for the given molecular formula ${\text{C}}_{\text{2}}{\text{H}}_{\text{6}}\text{S}$ and most acidic isomer should be identified among them.

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, basic nature is more. That means bulkiness increases the basic strength of the molecule. 

To draw: The all possible constitutional isomers for the molecular formula ${\text{C}}_{\text{2}}{\text{H}}_{\text{6}}\text{S}$
