9.13(b)Addition of hydrogen chloride to vinyl chloride gives the geminal dichloride 1,1-dichloroethane.(c)Since 1,1-dichloroethane can be prepared by adding 2 mol of hydrogen chloride to acetyleneas shown in the sample solution to part (a), frst convert 1,1-dibromoethane to acetylene bydehydrohalogenation.9.14The enol arises by addition of water to the triple bond.The mechanism described in the textbook Figure 9.6 is adapted to the case of 2-butyne hydration asshown:9.15Hydration of 1-octyne gives 2-octanone according to the equation that immediately precedes thisproblem in the text. Prepare 1-octyne as described in the solution to Problem 9.9, and then carry outits hydration in the presence of mercury(II) sulfate and sulfuric acid.Hydration of 4-octyne gives 4-octanone. Prepare 4-octyne as described in the solution toProblem 188.8.131.52Each of the carbons that are part of @CO2H groups was once part of a @C>C@unit. The twofragments CH3(CH2)4CO2H and HO2CCH2CH2CO
