Warm-up 15 (covering Sec. 5.12.3 – 5.14) DUE Thurs. 11/2 09-103 Fall 20061. Write the formulas of 2 trihalomethanes (THMs). (2 total – 1 for each)Any 2 of the following: CHCl3, CHCl2Br, CHClBr2, CHBr32. TRUE OR FALSE? CHCl3formation in water is not linked to chlorination. (1)FALSE. Chlorination causes the formation of HOCl in water. This HOCl can lead toformation of THMs like CHCl3 by reacting with humic acids, which are the organicbyproducts of plant or animal materials.3. In the printout from the gas chromatograph in Fig. 5.26b, why does CHBr3take longerto reach the detector than CHCl2Br? (Hint: Which compound would have thehigherboiling point?) (2 total)It has the highest molar mass(heaviest) (1). Since for compounds of relatively similar composition (like the THMs represented), a higher molar mass means a higher boiling point (1), CHBr3does not vaporize as readily and move as fast through the GC column.4. TRUE OR FALSE? Most of the bottled water currently sold in the U.S. meets higherquality standards than those imposed by the Food and Drug Administration (FDA). (
