For NEET 2026 preparation, focusing on types of reduction reactions, important reducing agents, and named reactions can significantly improve performance. Concepts such as gain of electrons, addition of hydrogen, and decrease in oxidation state are commonly tested. Regular practice of reduction-based questions and formulas not only strengthens conceptual clarity but also increases speed and accuracy in the NEET exam chemistry section.
What is Reduction?
Reduction is a chemical process in which a substance either:
Gains electrons
Loses oxygen
Gains hydrogen
Shows a decrease in oxidation number

Types of Reduction Reactions
Based on the chemical process involved, there are various ways for the occurrence of Reduction reactions:
1. Removal of Oxygen
Removal of oxygen from any compound leads to the formation of a reduction.
Example:
$\mathrm{FeO}+\mathrm{C} \rightarrow \mathrm{Fe}+\mathrm{CO}_2$
2. Addition of Hydrogen
If hydrogen is added to any substance, then reduction occurs:
Example:
$\mathrm{H}_2+\mathrm{I}_2 \rightarrow 2 \mathrm{HI}$
3. Gain of Electrons
The occurrence of electron transfer among species leads to reduction
Example:
$\mathrm{Cu}^{2+}+2 \mathrm{e}^{-} \rightarrow \mathrm{Cu}$
4. Oxidation Number Method
When the oxidation state of an element decreases during a chemical reaction, then reduction occurs
Important Reduction Reagents for NEET 2026
Refer to the reduction agents given below:
1. Lithium Aluminium Hydride $\left(\mathrm{LiAlH}_4\right)$
Lithium Aluminium hydride is a strong reducing agent. It is used to reduce esters, acids, aldehydes, ketones, and nitriles. $\left(\mathrm{LiAlH}_4\right)$ is highly reactive with water.
2. Sodium Borohydride $\left(\mathrm{NaBH}_4\right)$
Sodium Borohydride is a mild reducing agent. It mainly reduces aldehydes and ketones. It is Safer and more selective than $\left(\mathrm{LiAlH}_4\right)$
Both $\left(\mathrm{LiAlH}_4\right)$ and $\left(\mathrm{NaBH}_4\right)$ reagents are commonly used in organic chemistry mechanisms.
Named Reduction Reactions
These reactions are frequently asked in NEET exams:
1. Rosenmund Reduction
Rosenmund's reduction is a process in which acyl chlorides are converted to aldehydes in the presence of hydrogen and a catalyst
2. Clemmensen Reduction
The process through which aldehydes and ketones are converted into alkanes by using Zn(Hg) and HCl is Clemmensen Reduction.
3. Wolff Kishner Reduction
To convert carbonyl compounds into alkanes by using hydrazine Wolff Kisner Reductions process is used.
4. Birch Reduction
Birch reduction is the process in which aromatic rings reduce to non-aromatic compounds.
5. Stephen Reduction
Conversion of nitriles into aldehydes is carried out through the Stephen Reduction
