Markovnikov reaction is a
Nucleophilic substitution reaction
Electrophilic substitution reaction
SN1 reaction
Electrophilic addition reaction
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.

Concepts Used:
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:
- A new sigma bond from C=C is formed during the reaction in the arene nucleophile.
- Due to the breaking of the C-H sigma bond, a proton is removed.
- 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
