An unknown compound is treated with HBr in the dark. The product of this reaction is reacted with potassium t-butoxide. The product of reaction 2 is treated with HBr and peroxide. In reaction 4 the product of reaction 3 is treated with lithium acetylenide (C2H-). The product of reaction4 is reduced with hydrogen using platinum as a catalyst. This final product was determined to be n-pentylcyclopentane. What is the name of the original unknown compound?
What is the expected product of the reaction scheme below?
(10pts) Compound A, C10H16, was found to be optically active. On catalytic reduction over a palladium catalyst, 2 equivalents of hydrogen were absorbed, yielding compound B, CioH2o. On ozonolysis of A, two fragments were obtained. One fragment was identified as acetic acid (CHCOOH). The other fragment, compound C, was an optically active carboxylic acid, C8H14O2. Write reactions, and draw the correct structures for A-C, explain your answer in detail.

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.
