- a substance which have to be separated
- eluent
- adsorbent
- mixture of eluent and substances to be separated
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Column chromatography method used to isolate a single chemical compound from a mixture. Chromatography is able to separate substances based on differential adsorption of compounds to the adsorbent. Compounds move through the column at different rates, allowing them to be separated into fractions.
In column chromatography, the stationary phase, a solid adsorbent, is placed in a vertical glass (usually) column. The mobile phase or eluent is a solvent or a mixture of solvents along with substances to be separated and used to move the compounds through the column.

Organic Chemistry - Some Basic Principles and Techniques
Organic Chemistry is a subset of chemistry dealing with compounds of carbon. Therefore, we can say that Organic chemistry is the chemistry of carbon compounds and is 200-225 years old. Carbon forms bond with itself to form long chains of hydrocarbons, e.g.CH4, methane and CH3-CH3 ethane. Carbon has the ability to form carbon-carbon bonds quite elaborately. Polymers like polyethylene is a linear chain where hundreds of CH2 are linked together.
