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 ALL of the following questions.
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?
