Molecule-hydrogen ion in the method of molecular orbitals, states that result ?: a) One: binding b) One: binding or not depending on how it has been calculated c) Two: both binding d) Many: of increasing energy.Ozone (O3) has a nonzero dipole moment. In the molecule of O3 , one of the oxygen atoms is directly bonded to the other two, which are not bonded to each other. (a) Based on this information, state which of the following structures are possible for the ozone molecule: symmetric linear, nonsymmetric linear (for example, different OO bond lengths), and bent. (Note: Even an OO bond can have a bond dipole if the two oxygen atoms are bonded to different atoms or if only one of the oxygen atoms is bonded to a third atom.) (b) Use the VSEPR theory to predict which of the structures of part (a) is observed.
- A paper published in the research Journal Science in 2007 (S. Vallina and R. Simo, Science, Vol. 315, p. 506, January 26, 2007) reported studies of dimethylsulfide (DMS), an important green-house gas that is released by marine phytoplankton. This gas represents the largest natural source of atmospheric sulfur and a major precursor of hygroscopic (i.e., cloud-forming) particles in clean air over the remote oceans, thereby acting to reduce the amount of solar radiation that crosses the atmosphere and is absorbed by the ocean. (a) Sketch the Lewis structure of dimethylsulfide, CH3SCH3, and list the bond angles in the molecule. (b) Use electronegativities to decide where the positive and negative charges lie in the molecule. Is the molecule polar? (c) The mean seawater concentration of DMS in the ocean in the region between 15 north latitude and 15 south latitude is 2.7 nM (nanomolar). How many molecules of DMS are present in 1.0 m3 of seawater?Draw the Lewis electron dot structures for these molecules, including resonance structures where appropriate: (a) CS32 (b) CS2 (c) CS (d) predict the molecular shapes for CS32 and CS2 and explain how you arrived at your predictionsThe molecule shown below is called furan.

(e) TheC¬C¬C bond angles in furan are much smaller than thosein benzene. The likely reason is which of the following: (i) Thehybridization of the carbon atoms in furan is different fromthat in benzene, (ii) Furan does not have another resonancestructure equivalent to the one above, or (iii) The atoms in afive-membered ring are forced to adopt smaller angles than ina six-membered ring.

(Include a drawing in the explanation as needed)Represent the bonding in each molecule or ion by drawing the orbitals (hybridized and unhybridized) of each atom in the bond. Label the σ and π bonds and label each bond by the orbitals that it is made from. For instance, the C–H bond in CH4 would be made from the overlap of: C (sp3) – H (1 s). You may draw the hybridized sigma orbitals as sticks and the unhybridized p-orbitals as lobes for clairity and ease. a. HONO b. CH3 CCH c. C3 H4 d. C2 O4 2-
