Covalent bonds can be characterized on the basis of several bond parameters such as bond length, bond angle, bond order, and bond energy (also known as bond enthalpy). The higher the bond order is, the shorter the bond length. The bond angle order for the series, OF2, H2O, OCl2 is OCl2 > OH2 >OF2. Biology . Leo. 1 decade ago. Note: The bond pairs are usually represented by a solid line, whereas the lone pairs are represented by a lobe with two electrons. The bond angle order for the series, OF2, H2O, OCl2 is OCl2 > OH2 >OF2. NH2-, NH3, and NH4+ have H-N-H bond angles of 105, 107 and 109. All of these molecules have two bond pairs and two lone pairs. Bond angles also contribute to the shape of a molecule. How much smaller of a bond angle we get I’m not sure. 2 years ago Answers : (3) Arun ...
