Unformatted text preview: tetrahedron (109.5 degree)( Fig.B. ). The unshared pairs of electrons in ammonia and water serve to complete the vertices of the tetrahedral structure. Interactive molecules . Sulfates and phosphates also show tetrahedral structure ( Fig. A. ). H 2 S however has a bond angle of 92 degrees. Bond lengths are the distance between nuclei of bonded atoms. By adding the covalent radius ( Fig. C ) of the atoms participating in the bond the covalent bond length can be determined. For example a C-C bond has a length of 0.15 nm while a C-O bond has a length of 0.143 nm....
