So, is CH4 polar or nonpol B. A. Ionic compounds dissolve easily in water. Polar Bonds - In Polar Covalent chemical bonding, electrons are shared unequally since the more electronegative atom pulls the electron pair closer to itself and away from the less electronegative atom. Water is a universal solvent because it has the ability of dissolving more substances than any other liquid or solvent in the universe. (b) dipole-dipole interaction. Ammonia is asymmetrical molecule and has pyramidal shape. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. They are both super strong and pull super hard, and the rope doesn't move. so, SF4 is polar molecule.

Ammonia (NH3) is make hydrogen bonding and it effect extensive hydrogen bonding between molecules. The two electrically charged regions on either end of the molecule are called poles, similar to a magnet having a north and a south pole. Hydrogen Bonds - It is a type of polar covalent bonding between oxygen and hydrogen wherein the hydrogen develops a partial positive charge. As aforesaid, bent molecules are asymmetrical just like trigonal pyramids and that means that they are polar molecules.
