Your chemistry professor draws a number of molecules on the board: (1) CH4 ; (2) H2C=CH2 ; (3) H2C=C=CH2 ; and (4) H2C=C=C=CH2. You muse about all the molecules that chemists draw on a two-dimensional board and wonder which ones are actually planar, existing basically as they appear on the board, and which ones are not plane but rather three-dimensional. Answer the following questions. What is the geometry and hybridization of the carbon in CH4? What is the geometry and hybridization of each central carbon atom in the remaining molecules? Draw each molecule showing the bonds and identify each bond in all the molecules as s or p. What are the specific orbital overlaps (i.e., sp3-sp3) that are in each of the molecules? What are the bond angles for each central atom in each molecule? Which molecules are planar and which are non-planar?
