Chapter 6.2, Problem 4P

(a)

Interpretation Introduction

Interpretation:

The given set of carbo cations should be ranked from most to least stable.

Concept introduction:

Carbocation: It is carbon ion that bears a positive charge on it.

Leaving group: It is a fragment that leaves from a substrate with a pair of electrons via $heterolytic$ bond cleavage.

Carbocation stability order:

Resonance stabilization: Due to the delocalization of electrons within the molecule the overall energy becomes lower and makes that molecule more stable.

Nucleophile: Nucleophiles are electron rich compounds which donates electrons to electrophilic compounds which results in bond formation.

Nucleophilic nature depends on the negative charge present in the molecule, the solvent in which it present and the electronegativity of the atom.

Electrophile: Electrophiles are electron deficient compounds which accepts electrons from nucleophiles that results in bond formation.
