Some chemists believe that satisfaction of the octet ruleshould be the top criterion for choosing the dominant Lewisstructure of a molecule or ion. Other chemists believe thatachieving the best formal charges should be the top criterion.Consider the dihydrogen phosphate ion, H2PO4-, inwhich the H atoms are bonded to O atoms. (a) What is thepredicted dominant Lewis structure if satisfying the octetrule is the top criterion? (b) What is the predicted dominantLewis structure if achieving the best formal charges is the topcriterion?
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?
