Answer and solution
Answer 3
Solution
Chemistry ma’am · 3 steps
Sort each drug by what it does to the body: three of these calm the mind, one kills microbes.
- What tranquilizers do. Tranquilizers act on the central nervous system and relieve stress, anxiety or mild mental illness. Benzodiazepines and barbiturates (derivatives of barbituric acid, which act as hypnotics and sedatives) both fall in this class.
Drug Type Tranquilizer? Chlordiazepoxide (A, named "Chloroliazepoxide" in the question) benzodiazepine yes Veronal barbiturate (barbituric acid derivative) yes Valium (diazepam) benzodiazepine yes Salvarsan arsenic-based antimicrobial, used for syphilis no - The odd one out. Salvarsan was Paul Ehrlich's arsenic drug against the syphilis bacterium. It acts on microbes, not on the nervous system.
- So. Chlordiazepoxide, Veronal and Valium are tranquilizers, so the count is 3.
The common slip: 2. Treating Veronal only as a sleeping pill and leaving it out gives 2. Barbiturates are hypnotics, and NCERT lists them among tranquilizers.
The idea to keep. Learn tranquilizers in two families: benzodiazepines (chlordiazepoxide, valium) and barbiturates (veronal, amytal, nembutal, luminal, seconal). Salvarsan is an antimicrobial.
