Both bicyclo[3.3.1]nonane and bicyclo[2.2.1]heptane are saturated hydrocarbons composed of only 2° and 3° carbons. Recall that radical substitution generally takes place preferentially at a 3° carbon. Indeed, when bicyclo[3.3.1]nonane is treated with bromotrichloromethane under irradiation, substitution takes place 100% at the 3° carbon. Under the same conditions, however, no substitution is observed at the 3° carbon in bicyclo[2.2.1]heptane. Explain. Hint: Build molecular models of each of these compounds.

Q3. 2-Bromopentane, when treated with ‎ alcoholic KOH yields a mixture of three alkenes A, B and C. Identify A, B and C. Which is predominant? ‎ Q4 Which statement below about Sn1 reactions is incorrect? (A) SN1 reactions are stepwise and have intermediates. (B) The slow step in a SN1 reaction is formation of the carbocation intermediate. (C) SN1 reactions have first order kinetics which means only the alkyl halide is involved in the rate limiting step. (D) The products of a SN1 reaction will be a pair of enantiomers. (E) An aprotic solvent is best for Sn1 reactions as they tend to help stabilize carbocation intermediates.

I have the following data from an NMR scan. Five peaks; a doublet at about 0.8ppm (6H) a small single septet at about 1.5 ppm (1H), a triplet at 1.6 ppm (2H(, a singlet at about 2.1 ppm (3H), a triplet at about 4.4 ppm (2H). The molecular formula is C7H14O2. I calculated a degree of unsaturation of 1. I have tentatively identified the compound as methyl-4-methylbutanoate. I would appreciate any comments you care to make. Thank you.

Cyclopentadienyl anion (shown) has the following characteristic. O it is an anion with six π electrons, meeting the Hückel rule for aromaticity O it is not aromatic because it has only four electrons and the tetrahedral carbon prevents cyclic conjugation O it is an anion with six electrons, meeting the Hückel rule for anti-aromaticity O it is an anion with four electrons, meeting the Hückel rule for aromaticity
For centuries, Chinese herbal medicine has used extracts of Ephedra sinica to treat asthma. Ephedra as an"herbal supplement" has been implicated in the deaths of several athletes and has recently been banned as a dietary supplement. Phytochemical investigation of this plant resulted in isolation of ephedrine, a very potent dilator of the air passages of the lungs. Ephedrine also has profound effects on the cardiovascular system. The natu- rally occurring stereoisomer is levorotatory and has the following structure. Assign an Ror S configuration to each chiral center. H NHCH3 Ephedra sinica, the source of ephedrine, a potent bronchodilator. HO H CH3 Ephedrine [a -41
The compound shown reacts readily with HBr and adds water across at least of one of its double bonds. Why doesn't it behave like Benzene? 1. It is NOT a 4n + 2 system 2. severe steric interactions prevent it from being flat 3. It does NOT have a continous array of p orbitals to overlap 4. There are too many pi bonds to be aromatic
