Q16 / 75 · JEE Main 2020 (06 Sep Shift 1) · Chemistry

Kraft temperature is the temperature:

  • A
    below which the aqueous solution of detergents starts freezing.
  • B
    below which the formation of micelles takes place.
  • C
    above which the aqueous solution of detergents starts boiling.
  • Correct answer
    D
    above which the formation of micelles takes place.

Solution

(i) Micelles formation take place only above a particular temperature called as kraft temperature (TK) (ii) Concentration above which micelle formation become appreciable is critical micells concentration

Hence, the correct answer is option: 'D'.
