Question

In the given reaction sequence involving \(CHCl_3\), the end product \(C\) is used as:

• A. explosive
• B. hypnotic
• C. tear gas
• D. analgesic

Hint:

Chloral hydrate (\(CCl_3CH(OH)_2\)) is a hypnotic (sedative) drug used to induce sleep.

Answer 1

The Correct Option is B

The question involves the chemical behavior of \(CHCl_3\) (chloroform) and its use in a specific application after a reaction sequence. Let's analyze the provided options and understand why the correct answer is "hypnotic."

Chloroform is a well-known organic compound with the formula \(CHCl_3\). It is a colorless, sweet-smelling liquid that was historically used as an anesthetic and sedative due to its ability to depress the central nervous system. Owing to this property, its use in a specific function can be directly linked to its hypnotic effects.

1. Explosive: Compounds used as explosives typically release gases rapidly, causing an explosive reaction. Chloroform is not explosive and does not possess such properties.
2. Hypnotic: Chloroform has historically been used as a hypnotic agent due to its anesthetic properties, which induce sleepiness or unconsciousness, making this answer correct.
3. Tear Gas: Tear gases are chemical compounds that irritate the eyes, causing tears and discomfort. Chloroform does not have these irritant properties.
4. Analgesic: Analgesics relieve pain without causing a loss of consciousness. While chloroform has anesthetic properties, it is primarily known for making individuals unconscious rather than pain relief specifically.

Therefore, understanding the properties of chloroform and what functional use it has in practical applications leads to the conclusion that it is used as a hypnotic.
