200+ Organic Conversions || Aliphatic and Aromatic || Organic Chemistry Grade XII || For NEB Board Exam


Organic chemistry conversions refer to the various chemical reactions and processes that organic molecules can undergo to transform from one compound to another. These conversions involve the breaking and forming of chemical bonds in order to modify the molecular structure and properties of organic compounds.

Some of the most common organic chemistry conversions include:

Addition reactions:

These involve adding atoms or groups of atoms to a molecule, typically across a carbon-carbon double bond.

Elimination reactions:

These involve the removal of atoms or groups of atoms from a molecule, typically resulting in the formation of a double bond.

Substitution reactions:

These involve the replacement of one atom or group of atoms in a molecule with another.

Rearrangement reactions:

These involve the rearrangement of the atoms in a molecule to form a different isomer.

Oxidation and reduction reactions:

These involve the transfer of electrons between atoms in a molecule, resulting in the formation of new functional groups.

Organic chemistry conversions are essential in the synthesis of new organic compounds, as well as in the modification of existing compounds to improve their properties or functions. They are also important in the study of biological processes and in the development of pharmaceuticals, materials science, and other fields.

Organic Conversions

Here are some important things to remember while writing organic conversions:

Starting material:

Identify the starting material and its functional groups. It is important to correctly identify the functional groups in the starting material and the reactions that can be used to modify them.


Choose appropriate reagents for the desired conversion. The choice of reagents depends on the functional groups in the starting material and the desired product.


Understand the mechanism of the reaction. Knowing the mechanism of the reaction can help in predicting the stereochemistry and regiochemistry of the product.

Reaction conditions:

Determine the reaction conditions required for the conversion. Reaction conditions such as temperature, pressure, solvent choice, and catalysts can greatly affect the outcome of the reaction.

Yield and selectivity:

Consider the yield and selectivity of the conversion. A high yield and selectivity are desirable and can be achieved by choosing appropriate reagents, reaction conditions, and optimization of the reaction.

Product characterization:

Identify the product and its functional groups. It is important to verify the identity and purity of the product using various analytical techniques, such as NMR spectroscopy, mass spectrometry, and IR spectroscopy.

Reaction mechanism arrows:

Use reaction mechanism arrows to show the movement of electrons during the reaction. This helps in understanding the mechanism of the reaction and the formation of the product.

Writing conventions:

Use appropriate writing conventions, such as using the correct abbreviations for reagents and functional groups, and drawing clear and concise structures. This helps in communicating the reaction clearly and accurately.

Remembering these points while writing organic conversions can help in communicating the conversion effectively and accurately.
