The Correct Option is D

Solution and Explanation

To determine the type of reaction that aligns with Markovnikov's rule, we need a clear understanding of each reaction type:

  • Nucleophilic Substitution Reaction: This involves the replacement of a leaving group on a molecule by a nucleophile.
  • Electrophilic Substitution Reaction: Typically occurs in aromatic compounds, where an electrophile replaces a substituent on an aromatic ring.
  • Electrophilic Addition Reaction: Involves the addition of an electrophile to a site of unsaturation (e.g., double bond) in a molecule.
  • SN1 Reaction: A nucleophilic substitution reaction where the rate-determining step involves one molecule, leading to the formation of a carbocation.

The Markovnikov rule is associated with electrophilic addition reactions. When an unsymmetrical alkene reacts with a hydrogen halide (HX), the hydrogen atom (H) from the HX attaches to the less-substituted carbon atom, while the halide (X) attaches to the more-substituted carbon atom, forming more stable carbocations. Hence, Markovnikov's rule is exemplified in electrophilic addition reactions.

The correct description of Markovnikov's reaction aligns with an Electrophilic Addition Reaction.

Organic Chemistry – Some Basic Principles and Techniques - Reaction Mechanism

SN1 Reaction Mechanism:

SN1 reaction mechanism takes place by following three steps –

  • Formation of carbocation 
  • Attack of nucleophile 
  • Deprotonation 

SN2 Reaction Mechanism:

The SN2 reaction mechanism involves the nucleophilic substitution reaction of the leaving group (which generally consists of halide groups or other electron-withdrawing groups) with a nucleophile in a given organic compound.

Electrophilic Aromatic Substitution Reaction Mechanism:

The mechanism of an electrophilic aromatic substitution reaction contains three main components which are:

  1. A new sigma bond from C=C is formed during the reaction in the arene nucleophile.
  2. Due to the breaking of the C-H sigma bond, a proton is removed.
  3. The C=C bond is reformed and it restores the aromaticity of the compound.

Electrophilic Substitution Reaction Mechanism:

The electrophilic substitution reaction mechanism is composed of three steps, which will be discussed more below.

  • Electrophile Generation
  • Carbocation Formation
  • Proton Removal
