Correct Answer - Option 3 : Nucleophilic substitution reaction

Explanation:

• When CH3CH2Br reacts with aqueous NaOH solution, CH3CH2OH is produced.
• This is a nucleophilic substitution reaction.
• The reaction follows SN2 pathway.
• The nucleophile OH- attacks on the nucleophilic carbon atom from the backside and bromide starts to depart from the same carbon atom.

Nucleophilic substitution reactions-

Substitution reactions are the types of reactions where a nucleophile is the attacking reagents.

• There are three types of substitution reactions depending on the nature of the substrate.
• Nucleophilic substitution at saturated carbon.
• Nucleophilic acyl substitution
• Nucleophilic aromatic substitution.
• SN- Unimolecular nucleophilic substitution:
• Depends upon the concentration of the substrate.
• Is independent of the concentration of the nucleophile.
• Follows first-order kinetics.
• SN2- bimolecular nucleophilic substitution.
• the rate depends on the concentration of both the reactant and the substrate.
