Question:
Two compounds I and II are eluted by column chromatography (adsorption of I > II). Which one of following is a correct statement ?
Two compounds I and II are eluted by column chromatography (adsorption of I > II). Which one of following is a correct statement ?
Updated On: Sep 30, 2024
- I moves faster and has higher $R_f$ value than $II$
- II moves faster and has higher $R_f$ value than $I$
- I moves slower and has higher $R_f$ value than $ II$
- II moves slower and has higher $R_f$ value than $I$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The $R_{r}$ value is the distance travelled by the substance divided by the distance travelled by the solvent front. As $I$ adsorbs more than II, therefore, II will move faster and will have higher $R_{f}$ than 1 .

- Given below are two statements :
Statement I : The boiling point of three isomeric pentanes follows the order
n-pentane > isopentane > neopentane
Statement II : When branching increases, the molecule attains a shape of sphere. This results in smaller surface area for contact, due to which the intermolecular forces between the spherical molecules are weak, thereby lowering the boiling point.
In the light of the above statements, choose the most appropriate answer from the options given below :- NEET (UG) - 2024

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.
