- a) which bond is present in alcohols but not alkanes? b) is this band strong or weak (in terms of spectra)? c) what is different about C=O and O-H bonds compared with C=C or C≡C bonds that show weaker signals?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?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?
- Draw Lewis structures and condensed structural formulas for the four alcohols with the molecular formula C4H10O.

Label them correctly.The pentadienyl radical, H2C“CH¬CH“CH¬CH2#, has its unpaired electron delocalized over three carbon atoms.(a) Use resonance forms to show which three carbon atoms bear the unpaired electron.(b) How many MOs are there in the molecular orbital picture of the pentadienyl radical?
- The naphthalene molecule has a structure that corre- sponds to two benzene molecules fused together: The ™ electrons in this molecule are delocalized over the entire molecule. The wavelength of maximum absorption in benzene is 255 nm. Will the corresponding wavelength in naphthalene be shorter or longer than 255 nm?Draw Lewis structures and condensed structural formulas for the four alcohols with the molecular formula C4H10O. Classify each alcohol as primary, secondary, or tertiary. (Hint: First consider the connectivity of the four carbon atoms; they can be bonded either four in a chain or three in a chain with the fourth carbon as a branch on the middle carbon. Then consider the points at which the iOH group can be bonded to each carbon chain.)The average bond energy (enthalpy) for a C=CC=C double bond is 614 kJ/molkJ/mol and that of a C−CC−C single bond is 348 kJ/molkJ/mol. Estimate the energy needed to break only the ππ bond of the double bond of 2-butene. Express your answer numerically in joules per molecule.
