Organic Chemistry - Some Basic Principles and Techniques. The C-N bond distance, for which reson- ance theory predicts a considerable shortening, ought to yield more information about the relative magnitudes of resonance and hybridization in nitrobenzene. There are alternating single and double carbon-carbon bonds. Benzene is built from hydrogen atoms (1s 1) and carbon atoms (1s 2 2s 2 2p x 1 2p y 1).. Each carbon atom has to join to three other atoms (one hydrogen and two carbons) and doesn't have enough unpaired electrons to form the required number of bonds, so it needs to promote one of the 2s 2 pair into the empty 2p z orbital. The electron cloud geometry would be tetrahedral and the molecular geometry would still be bent, but with a smaller bond angle (about 109). This hybridization is a must to achieve the bond angle #120^@# which is found in benzene rings. Carbon atoms in the benzene ring have a trigonal planar geometry around them since the carry bonds with three other groups and therefore, the hybridization is #sp^2#. E) The pi bonds of carbon involve sp 2 orbitals. Hybridization of C in benzene=sp2. Hence option A is the right answer. Further, the carbon atom lacks the required number of unpaired electrons to for… Building the orbital model. What is the hybridization of the carbon atom in the following structures: a) ketone, b)aldehydes, c) carboxylic acids, d) alcohols, e) esters, f) ethers? As you can see, every carbon atom in...
