A. Draw the correct Lewis structure of CH3CONH2. B. Which orbitals form the sigma bond between the carbons? Lewis Structure: It can be used to represent any bonded molecule or a coordination complex. It clearly shows the lone pairs and bond pairs pres...
A novel hydrated cobalt tetraborate complex NH4[Co(NH3)5(H2O)][B4O5(OH)4]2路6H2O, was synthesized by the reaction of NH4-borate aqueous with CoCl2 and its structure was determined by single crystal X-ray diffraction. The crystal system of this complex is orthorhombic, the space group is...
1. Count the total number of valence electrons (including all ligands, and the central atom). 2. Create a skeleton of the molecule by connecting all ligands to the central atom with one bonding electron pair. 3. Complete the electron octet on the ligands. ...
The octahedral complex tetraammine(chloroaquo)cobalt(III) dichloride is shown to be the HCl hydrolysis product of both P1,2-bidentate tetraammine(pyrophosphato)cobalt(III) [CO(NH3)4HP207 or CoPP] and bidentate tetraammine(phosphato)cobalt(III) [Co(NH3)4P04or CoP]. The complex crystallizes...
