Water Molecule and its Structure |
Water is a colourless, odourless clear liquid with a molecular formula of H2O ie; one oxygen atom is bonded to two hydrogen atom by covalent bond (Electrovalent bond). As there are two lone pairs in Oxygen and due to high electronegative character of Oxygen there exist a feable negative charge (delta negative charge) in the Oxygen exist a feable negative charge in the oxygen of water molecule. Being Hydrogen is electro positive in nature and is covalently connect with highly electro negative Oxygen, the bond pair will be more close to the oxygen therefore there arise a delta positive charge in these hydrogen atoms of water molecule. Because of these electric charge on Hydrogen and Oxygen. One molecule of water feebly connected with the other molecule by Hydrogen bridge bond. This make this intermolecular additional Hydrogen bond other than the intermolecular force makes water as liquid. The bond angle of water molecule 104.50 and bond length is 96 nm. According to balance bond theory it also has two lone pair of electrons. The shape of the molecule is inverted V shape as shown below.
