11.1 What is wrong with the use of such names as “isopropanol” and “tert-butanol”? Answer: We should say them as “isopropyl alcohol” and “tert-butyl alcohol”. 11.2 Give bond-line formulas and appropriate names for all of the alcohols and ethers with the formulas (a) C 3 H 8 OH and (b) C 4 H 10 O (a) CH 3 CH 2 CH 2 OH propanol H 3 C C H CH 3 OH 2-propanol CH 3 OCH 2 CH 3 Ethyl methyl ether (b) CH 3 CH 2 CH 2 CH 2 OH butanol H 3 C H 2 C C H OH CH 3 2-butanol C OH H 3 C H 3 C H 3 C tert-butyl alcohol CH 3 OCH 2 CH 2 CH 3 propyl methyl ether CH 3 CH 2 OCH 2 CH 3 diethyl ether H 3 C C H CH 3 OCH 3 isopropyl methy ether OH 2-methyl-1-propanol 11.3 1,2-Propanediol and 1,3-propanediol(propylene glycol and trimethylene glycol, respectively; see Table11.2)have higher boiling points than any of the butyl alcohols, even though all of the compounds have roughly the same molecular weight. How can you explain this observation. The diols have two –OH, so it can form stronger hydrogen bonding. Therefore, 1,2-Propanediol and 1,3-propanediol have higher boiling points than any of the butyl alcohols. 11.4 What products would you expect from acid-catalyzed hydration of each of the following alkene? (a) Ethene (c)2-Methylpropene (b)Propene (d)2-Methyl-1-butene (a) H 3 O OH
