1.	Assertion (A): In paper chromatography, the compound is identify on the base of R_(f) value.Reason (R ): The R_(f) value of every compound is definate and constant
Answer» Statement (A) and Reason (R ) both are right. Statement (R ) is correct explanation of statement (A) Statement (A) and Reason (R ) both are right, but (R ) is not correct explanation of statement (A) Both Statement (A) and (R ) are wrong Statement (A) is right but statement (R ) is wrong Solution :`R_(f)` is retardation factor `R_(f) = ("Distance moved by the substance from BASE LINE")/("Distance moved by the solvent from base line")` `R_(f)` vlaue of EVERY compound is definite and constant like boiling POINT, melting point, density etc. So, on the base of `R_(f)` value to get the name of compound
