solve the road mab with explanation 16. ROAD MAP: Compounds A, B, and Care constitutional isomers. Treatment of A or B with potassium tert-butoxide gives the same alkene D. If the base is changed to a less sterically hindered base such as sodium ethoxide, A and C give the same alkene E as the major product. Treatment of C (spectroscopic data given on next page) with potassium tert-butoxide gives yet another alkene F as a minor product. Compound B reacts...
ROAD MAP. Compound A has the chemical formula CHio. Treatment of A with HS0, and H:0 produces ohol B However, when A undergoes hydroboration with 9-BBN followed by oxidation, secondary alcohol C with chemical formula CsHi20 is formed (H NMR provided below). If either Compound A or Compound B is alkyl halide D. When Compound D is reacted with sodium in THF at room temperature, no reaction occurs. Upon treatment of compound C with sodium hydride pound 12.. alc followed...

12 ROAD MAP: Compound A has the chemical formula CHn. Treatment of A with H,SO, and HO produces sertiary alcohol B. However, when A undergoes hvdroboration with 9-BBN followed by oxidation secondary alcohol C is formed. When Compound A is reacted with HCl alkyl halide D is produced. When D is reacted with water at room temperature alcohol B is produced. When Compound D is reacted with sodium methoxide in TH at room temperature, no reaction occurs. Upon treatment of...
1. please check what is wrong. Thank you! Determine the product formed when each compound is treated with Br2 and FeBr3. Drag the atom labels to their appropriate positions.
