Question

Given below are two statements: Statement-I: Retardation factor ( R f ) 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

R f = retardation factor Rf = ( textDistance travelled by the substance from reference line(c.m)/ textDistance travelled by the solvent from reference line (c. m)) Note: R f value of different compounds are different

Q. Given below are two statements:
Statement-I : Retardation factor $(R_{f})$ 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:

Statement-I is true but statement-II is false

Both statement-I and statement-II are true

Both statement-I and statement-II are false

Statement-I is false but statement-II is true

$R_{f} =$ retardation factor

$R_{f} = \frac{Distance travelled by the substance from reference line(c.m)}{Distance travelled by the solvent from reference line (c. m)}$

Note $: R_{f}$ value of different compounds are different
