Increasing order of dipole moment isA. `CF_(4) lt NH_(3) lt NF_(3) lt H_(2)O`B. `CF_(4) lt NH_(3) lt H_(2)O lt NF_(3)`C. `CF_(4) lt NF_(3) lt H_(2)O lt NH_(3)`D. `CF_(4) lt NF_(3) lt NH_(3) lt H_(2)O` |
Answer» Correct Answer - d `CF_(4)` is symmetrical and non poler `mu = 0`. In `NF_(3)`.the resultant of three `N - F` dipole oppose the effect of lone pairs of electrons of `N` -atom , whereas in `NH_(3)`, the effect of lone pairs of electrons of `N` atom and resultant of three `N - H`dipoles are in the same direction. Therefore`mu_(NH_(3)) (=1.46 D)gt mu_(NH_(3)` `mu_(H_(2)O) = 1.85 D` |
