(a) Here reactants are favored.

(b) In this conversion the reactants are favored.

(c) products are favoured.

(d) Reactants are favored.

(d)

Step by step solution

Step 1: Reactants are favored.

As the reactants are neutral species, and always the stability of neutral species is more than the ions. The reactants are neutral and the products are cation and anion. So, the reactants are favoured.

Step 2: Reactants are favoured.

The products are not favoured because the aromaticity of the pyrole is destroyed. In the reactants the lone pair of electrons participate in conjugation and the molecule is aromatic. After the reaction the molecule loses aromaticity.

As the reactants are neutral species, and always the stability of neutral species is more than the ions.

The reactants are neutral and the products are cation and anion.

So, the reactants are favoured.

Products are favored.

The product will be more stable because positive charge will be more stable in sp³ hybridised atom then sp² hybridised atom

Step 4: Reactants are favored.

As the reactants are neutral species, and always the stability of neutral species is more than the ions. The reactants are neutral and the products are cation and anion.

So, the reactants are favoured.
