Question

What is meant by derivative in Chemistry?

Answer 1

Hint: In the past, derivative also meant a compound that can be believed to develop from another compound if one atom or group of atoms is substituted with another atom or group of atoms, but current chemical language now utilizes the word structural analogue to avoid ambiguity. In organic chemistry, the term "structural analogue" is commonly used.

Complete answer:
In chemistry, a derivative is a substance that is created via a chemical reaction from another component. It is widely used in organic chemistry, and it is made by exchanging one atom or a group of atoms with another atom or a group of atoms from the parent chemical.
To make analysis easier, chemical derivatives might be utilized. Melting point (MP) analysis, for example, can help identify a variety of organic substances.
If a table of derivative melting point values is available, a crystalline derivative, such as a semicarbazone or $2,4-$ dinitrophenylhydrazone (produced from aldehydes or ketones), can be created as a quick manner of establishing the identity of the parent chemical. Such approaches were commonly utilized before the advent of spectroscopic analysis.
With the help of derivatives in chemistry, we can find the concentration of an element in a product.
Derivatization is a chemical process that turns a chemical molecule into a derivative (the reaction's derivative) with a comparable chemical structure.

Note:
In general, the derivatization reaction involves a specific functional group of the compound, which turns the educt into a derivative with differing reactivity, solubility, boiling point, melting temperature, aggregation state, or chemical composition. The novel chemical properties that result can be used to quantify or separate the educt.
