Multiple choice

The increasing order of dipole moment is

  1. CH3I < CH3Br < CH3Cl < CH3F

  2. CH3I > CH3Br > CH3Cl > CH3F

  3. CH3I < CH3Br < CH3F < CH3Cl

  4. CH3I < CH3Br > CH3F < CH3Cl

C Correct answer
Explanation

This option is correct because in the case of CH3F, magnitude of charge is the highest, but in the case of CH3Cl, the charge is almost the same as that of CH3F, but the separation between the charges overpowers. Hence, the magnitude of dipole moment of CH3Cl is greater than that of CH3F. Hence, the correct order is CH3I < CH3Br < CH3F < CH3Cl.
