To determine which of the given compounds is an example of a hypnotic drug, we need to understand what hypnotic drugs are and then evaluate each option:
Definition of Hypnotic Drugs: Hypnotic drugs, also known as sedative-hypnotics, are a class of drugs whose primary function is to induce sleep and maintain it. They are often used in the treatment of insomnia and other sleep-related disorders.
Based on this analysis, the correct answer is Amytal, which is a hypnotic drug.
Seldane→ Antihistamine
Amytal → Barbiturate (Hypnotic)
Aspartame → Artificial sweetener
Prontosil → Antibiotics
So, the correct option is (B): Amytal.
What will be the equilibrium constant of the given reaction carried out in a \(5 \,L\) vessel and having equilibrium amounts of \(A_2\) and \(A\) as \(0.5\) mole and \(2 \times 10^{-6}\) mole respectively?
The reaction : \(A_2 \rightleftharpoons 2A\)

Cobalt chloride when dissolved in water forms pink colored complex $X$ which has octahedral geometry. This solution on treating with cone $HCl$ forms deep blue complex, $\underline{Y}$ which has a $\underline{Z}$ geometry $X, Y$ and $Z$, respectively, are
