Choose the two alkyl bromides and the hydrogenation method that must be used to synthesize these alkenes from acetylene. Enter your answer as two letters in alphabetical order, followed by a number; i.e. ac2, not ca2. Do not use punctuation. Alkyl Halides a. CH3CH₂Br b. CH3(CH₂)4Br c. CH3(CH2)sBr d. CH3(CH₂) Br e. CH3(CH₂)7Br f. CH₂(CH₂) Br g. CH3(CH₂)12Br Hydrogenation Method 1. H₂, Lindlar's catalyst 2. Na, NH3 (1) CH3 Alkene #1: H₂C Alkene #2: H₂C CH3

Write the structural formula of the organic product for the given reaction between an alkyne and an alkyl halide. The alkyne group is shown and should be entered as "CC" without the triple bond. Enter CC before associated HH atoms (e.g., CH3CH2CH2OCHCHCH3).                      1.NaNH2 CH3CH2CCH------>                     2. CH3CH2b2

Compound A is first treated with ylide Y and then reacted with Rh and hydrogen gas. Using the spectroscopic data provided, what is the structure of Compound A?
