Study the following and pick up the correct statements:
I. Opioids are obtained from Cannabis sativa
II. Heroin is obtained by the acetylation of Morphine
III. Barbiturates cause sleeplessness
IV. Benzodiazepines are tranquilizers
Study the following and pick up the correct statements:
I. Opioids are obtained from Cannabis sativa
II. Heroin is obtained by the acetylation of Morphine
III. Barbiturates cause sleeplessness
IV. Benzodiazepines are tranquilizers
Show Hint
- I, II
- II, IV
- I, IV
- III, IV
The Correct Option is B
Solution and Explanation
- Statement I is incorrect because opioids are not obtained from Cannabis sativa, which is mainly the source of cannabinoids.
- Statement II is correct because heroin is synthesized by acetylating morphine.
- Statement III is incorrect because barbiturates typically induce sleep, not sleeplessness.
- Statement IV is correct as benzodiazepines are indeed tranquilizers.

For a first order decomposition of a certain reaction, rate constant is given by the equation
\(\log k(s⁻¹) = 7.14 - \frac{1 \times 10^4 K}{T}\). The activation energy of the reaction (in kJ mol⁻¹) is (\(R = 8.3 J K⁻¹ mol⁻¹\))
Note: The provided value for R is 8.3. We will use the more precise value R=8.314 J K⁻¹ mol⁻¹ for accuracy, as is standard.- TS EAMCET - 2025
