A) in \[N{{H}_{3}}\] as well as in \[N{{F}_{3}}\] the atomic dipole and bond dipole are in the same direction
B) in \[N{{H}_{3}}\] the atomic dipole and bond dipole are in the same direction whereas in \[N{{F}_{3}}\] these are in opposite directions
C) in \[N{{H}_{3}}\] as well as \[N{{F}_{3}}\] the atomic dipole and bond dipole are in opposite directions
D) in \[N{{H}_{3}}\] the atomic dipole and bond dipole are in the opposite directions whereas in \[N{{F}_{3}}\]these are in the same directions
Correct Answer: B
Solution :
Electronegativity of N is greater than that of H, but in \[N{{F}_{3}}\] electronegativity of F is greater than that of N. So, in \[N{{H}_{3}}\] the atomic dipole and bond dipole are in the same direction whereas in \[N{{F}_{3}}\] these are in opposite directions. |
