Question =  Is AsH3 polar or  nonpolar  ? [math]NCl_3[/math] has the same geometry as ammonia, which is pyramidal with a [math]C_{3v}[/math] point group. Relevance. The three chloride atoms have a negative charge, and the one boron in the center has an equal but positive charge. It is polar, because its charges are distributed asymmetrically and its geometric shape is asymmetrical. More electronegative atom attracts the bonded electron pairs slightly more towards itself and gains partial negative charge whereas the other gains partial positive charge. Obviously there is a lone pair on the central N atom - is this taken into account when deciding whether molecules are polar or not? Boron trichloride, or BCl3, is nonpolar. This leads to electron-electron repulsion which results in a bent structure, thereby causing an unequal distribution of charge within the molecule and creating a permanent dipole. As a result, the dipole moment of N-Cl comes out to be non zero. Note: It is possible to have an existence of polar bonds in a nonpolar molecule, but due to symmetrical shape, these polarities get canceled with each other resulting in a nonpolar molecule. So let’s discuss everything in detail what’s the logic and why somewhere NF3 is polar and sometimes nonpolar. Answer =  TeCl4 (  Tellurium tetrachloride )   is Polar What is polar and non-polar?
