(You may need to draw Lewis structures and geometric sketches to do so.) a. CO 2 b. OF 2 c. CCl 4 d. CH 2 Cl 2 e. HCN. Solution: a. The Lewis structure for CO 2 is
Dec 31, 2011 · When drawing Lewis structures we don't use dots and crosses. That is an antiquated approach. The reason is that in a compound, all of the electrons belong to the entire molecule, not to individual atoms. This is the influence that molecular orbital theory has had on Lewis structures: no crosses, only dots (and dashes for bonding pairs.) Q. Draw the orbital diagram for ion N 3-. Q. Draw the orbital diagrams (box/line notation) for the following species:Mn2+Cu See all problems in Orbital Diagrams
Magnetic Behavior: If all the molecular orbitals in species are spin paired, the substance is diamagneti. But if one or more molecular orbitals are singly occupied it is paramagnetic. For Example, if we look at CO Molecule, it is diamagnetic as all the electron in CO are paired as in the figure below: Fig. No. 9 Molecular Orbital Diagram for CO

A) O2^2-B) Ne2^2+ C) O2^2+ D) F2^2+ E) None of the above are paramagnetic; 3) Draw the molecular orbital diagram needed, and determine which of the following is paramagnetic. A) B2^2+ B) B2^2-C) N2^2+ D) C2^2-E) B2
Second period elements (C,N,O,F) cannot have more than 8 electrons around the central atom. This is due to the lack of empty d orbitals and hence these elements can not have expanded octet. Elements from the third period onwards can have an expanded octet due to the introduction of d orbitals in these periods. 3. Q. Oxygen forms covalent bonds with carbon and sulfur, but forms ionic bonds with sodium and magnesium. What can be inferred about the behavior of oxygen when bonding with different elements?
