MCQ
Given below are two statements : One is labelled as Assertion $A$ and the other is labelled as Reason $R$

Assertion $A$ : Thin layer chromatography is an adsorption chromatography.

Reason $R$: A thin layer of silica gel is spread over a glass plate of suitable size in thin layer chromatography which acts as an adsorbent. In the light of the above statements, choose the correct answer from the options given below.

  • Both $A$ and $R$ are true and $R$ is the correct explanation of $A.$
  • B
    Both $A$ and $R$ are true but $R$ is $NOT$ the correct explanation of $A$
  • C
    $A$ is true but $R$ is false
  • D
    $A$ is false but $R$ is true

Answer

Correct option: A.
Both $A$ and $R$ are true and $R$ is the correct explanation of $A.$
a
Theory based

Thin layer chromoatography $(TLC)$ is another type of adsorption chromatography, which involve sepration of substance of a mixture ovel a thin layer of an adsorbent coated on glass plate. A thin layer (about $0.2\,mm$ thick) of an adsorbent (silica gel) or (Alumina) in spread overa glass plate of suitable size. Hence Assertion $(A)$ is correct and Reason $(R)$ is correct explanation of $(A)$
