Which of the following molecule has the maximum dipole moment?
Options
- ANH 3
- BCS 2
- CC 2 H 6
- DNCl 3
Correct answer
A. NH 3
Step-by-step solution
The dipole moment depends on the charge and distance between the central atom and side atoms. But the charge is more prominent than distance. It is determined as polar and non-polar molecules. It can be determined by the geometry of the molecule. In case of NCl 3   &   NH 3 the electronegativity difference between N - H is higher than the electronegativity difference between N - Cl bond so the shared pair of electrons shifted towards chlorine in case of NCl 3 and in case of NH 3 it will be towards Nit
