Solution

Chemistry ma’am · 3 steps

Sort each name into its family first: sweetener, medicine, or a sugar that nature already makes.

  1. What counts. An artificial sweetener is a man-made compound that tastes sweet but adds almost no calories. Natural sugars like sucrose or lactose do not count, even though they are sweet.
    OptionWhat it isUsed as
    Bithionala phenolic compound added to soapsantiseptic
    Alitamea synthetic dipeptide-based compound, about 2000 times sweeter than cane sugarartificial sweetener
    Salvarsanan arsenic-based drug made by Paul Ehrlichantimicrobial (treatment of syphilis)
    Lactosemilk sugar, a disaccharide of glucose and galactosenatural sugar, not artificial
  2. About alitame. Alitame is more heat-stable than aspartame, so it can be used in cooked food. Its drawback is that the sweetness is hard to control in food.
  3. So. Only (b), alitame, is an artificial sweetener.

The idea to keep. Learn the artificial sweeteners as one set: saccharin, aspartame, sucralose and alitame. If a name is not on that list, check whether it is a drug, an antiseptic or a natural sugar.
