JEE Main 30 January 2024, Shift 2, Chemistry Q62

Question 62 of 90 in this shift, Chemistry question 2 of 30, Section A.

Given below are two statements: Statement - I: Since Fluorine is more electronegative than nitrogen, the net dipole moment of NF3\mathrm{NF_3} is greater than NH3\mathrm{NH_3}. Statement - II: In NH3\mathrm{NH_3}, the orbital dipole due to lone pair and the dipole moment of NH bonds are in opposite direction, but in NF3\mathrm{NF_3} the orbital dipole due to lone pair and dipole moments of N-F bonds are in same direction. In the light of the above statements, choose the most appropriate from the options given below:
  1. (1)Both Statement I and Statement II are true.
  2. (2)Both Statement I and Statement II are false.Official answer
  3. (3)Statement I is true but Statement II is false.
