JEE Mains · Chemistry · STD 11 - 8.3. Organic chemistry purification and characterization
Given below are two statements Statement \(-I :\) Retardation factor \(\left( R _{ f }\right)\) can be measured in meter/centimeter. Statement \(-II :\) \(R _{ f }\) value of a compound remains constant in all solvents. Choose the most appropriate answer from the options given below
- A Statement\(-I\) is true but statement\(-II\) is false
- B Both statement\(-I\) and statement\(-II\) are true
- C Both statement\(-I\) and statement\(-II\) are false
- D Statement\(-I\) is false but statement-II is true
Answer & Solution
Correct Answer
(C) Both statement\(-I\) and statement\(-II\) are false
Step-by-step Solution
Detailed explanation
\(R _{ f }=\) retardation factor Distance travelled by the substance from \(R _{ f }=\frac{\text { reference line }( c \cdot m )}{\text { Distan ce travelled by the solvent from }}\) reference line \((c.m)\) Note : \(R _{ f }\) value of different compounds are different.
