![]() In case of hydrogen fluoride (HF molecules), it is chemically bounded due to covalent bond. therefore, it is more possibility to make hydrogen bonding.įor example, H.F, (relationship between Hydrogen fluoride) Hydrogen bond occur between molecules that are atmos are bound to highly electronegative elements. ![]() hydrogen bonding is also called intermolecular forces between two molecules. this type of forces is called hydrogen bonding. As a result attraction forces is produced between them. partial positive charge of hydrogen are attracted with partial negative charge of other molecules. there are two highly polarized molecules. in this case, partial positive charge appear on hydrogen and partial negative chare appear on nitrogen. and it has hydrogen bonding.Īs a result, this molecules is called highly polarized molecules. so, you can say that, it is polar molecules. therefore, the large difference in electronegativity between the N atom and H atom, N-O, N-F atoms leads to highly polar covalent bond. the difference of electronegativity between atoms is (0.8). it mean nitrogen has highly electronegative atoms compare with hydrogen. you know that, the value of electronegative of nitrogen is 3.0 and the value electronegative of hydrogen is 2.2. the element has at least one loan pair electron.Īccording to difference in electronegativity between two atoms., suc as, N and H. ![]() these are the simple basic concepts of hydrogen bonding. then this types of bonds is know as hydrogen bonding.
