NF3 is polar because, according to its Lewis structure, the molecule forms a pyramidal shape. hope this helps (a) Molecules are always randomly distributed in the liquid state in the absence of an electric field. Also, polar solvents are better at dissolving polar substances, and nonpolar solvents are better at dissolving nonpolar substances. AB 5 E 1 = five outer atoms bonded to center + one lone pair on center = square pyramidal: XIII. the bond is polar, the molecule is polar, and if the bond is nonpolar, The shapes of larger molecules having more than one central positions, the carbon-oxygen bonds in carbonate are molecule. (b) When an electric field is applied, polar molecules like HF will align to the dipoles with the field direction. (b) When an electric field is applied, polar molecules like HF will align to the dipoles with the field direction. This problem has been solved! PH3 is a polar compound due to the presence of a lone pair of electrons with an electron-electron repulsion which gives rise to an overall “bent” structure. Start studying Polar vs. Nonpolar. This situation further results in a dipole moment which can be seen throughout the molecule structure. At this point, there will be 3 dipoles "pointing" at different directions.
