JEE Mains · Chemistry · STD 11 - 4. Chemical bonding and molecular structure
Given below are two statements:
Statement-\(I\): Since fluorine is more electronegative than nitrogen, the net dipole moment of \(\mathrm{NF}_3\) is greater than \(\mathrm{NH}_3\).
Statement-\(II\): In \(\mathrm{NH}_3\), the orbital dipole due to lone pair and the dipole moment of \(\mathrm{NH}\) bonds are in opposite direction, but in \(\mathrm{NF}_3\) 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.
- A Statement \(I\) is true but Statement \(II\) is false.
- B Both Statement \(I\) and Statement \(II\) are false.
- C Both statement \(I\) and Statement \(II\) is are true.
- D Statement \(I\) is false but Statement \(II\) is are true.
