Given below are two statements: Statement-I: Retardation factor R f can be measured in meter/centimetre. Statement-II: R f value of a compound remains constant in all solvents. Choose the most appropriate answer from the options given below:

Options

  1. AStatement-I is true but statement-II is false
  2. BBoth statement-I and statement-II are true
  3. CBoth statement-I and statement-II are false
  4. DStatement-I is false but statement-II is true

Correct answer

C. Both statement-I and statement-II are false

Step-by-step solution

R f = retardation factor R f = Distance   travelled   by   the   substance   from   reference   line   cm Distance   travelled   by   the   solvent   from   reference   line   cm Note: R f value of different compounds are different.
