    Cyclic Alkyne reaction with KMnO4 and O3

    Molecule 1: 5 carbon ring, carbon 1 has a carbon attached which also is triple bonded to another carbon (this end carbon just has a H attached.) There is also a double bond between carbons 1 and 2 in the ring. Predict the product when this reacts with KMnO4 in H30+. Molecule 2: I have a 6 carbon ring. C1 has a C which is

    Determine the Functional Group

    For problems 1 through 3, determine the functional group from the following spectra. There is only one functional group per compound. Determine whether the compound is aromatic or not aromatic. Follow the instructions attached.

    Aromatic Compounds and Cycloheptatrienyl

    Explain the following: a.) The cycloheptatrienyl anion is antiaromatic, whereas the cyclononatetraenyl anion is planar (in spite of the angle stain involved) and appears to be aromatic. b.) Although [16] annulene is not aromatic, it adds two electrons readily to form an aromatic dianion.

    Retrosynthesis of a Molecule

    Provide a retrosynthetic analysis and the forward synthsis of the following molecule, starting from commercially available compounds. The retrosynthesis should clearly identify the synthons and their synthetic equivalents. Functional group interconversions and bond disconnections should be clearly indicated where appropriate. Th

    Material purified from safflower oil

    Provide me with your exact logic used to get the answer. A mysterious material was purified from safflower oil (hint: full of fatty acids). Upon ozonolysis it gave the following compounds in their respective molar ratios. Draw the structure of the mysterious material and give me its common name. 3 moles CHOCH2CHO 1 mol

    C=C Stretching Mode

    Explain why the C=C stretching mode gives rise to a rather weak IR band in 1-methylcyclohexane, while in its isomer, methylenecyclohexene, the band is of medium to strong intensity.

    Perkin and related reactions

    There are numerous condensations that are closely related to the Perkin reaction. Among these are the aldol /3Badv/, and /A3a/, Knoevenagel, Claisen, and Dickmann condensations. What general class of compounds can be prepared using each of these well-known reactions?

    Explanation of Ratios

    In an unsymmetrical alkene, the boron atom adds predominantly to the least substituted carbon atom. For example, 2-methyl-2-butene gives the products shown below. CH3-C-CH2-CH3 (also has a CH3 single bonded above the C and a BH2 single bonded below the C) 2% CH3-CH-C-CH3 (also has a CH3 single bonded above the C in the CH
