Solution and Explanation
The question asks for the chemical name of "laughing gas." Let's analyze the given options and identify the correct answer:
- Nitrogen dioxide (NO2): This is a reddish-brown gas known for its role in air pollution and as a precursor to acid rain. It is not related to laughing or any anesthetic effect.
- Nitric oxide (NO): This gas is a signaling molecule in the human body and is not used for anesthesia or laughter-inducing purposes.
- Nitrogen peroxide (N2O4): This is a dimer of nitrogen dioxide and does not have any anesthetic properties.
- Nitrous oxide (N2O): This is commonly known as "laughing gas." It is used in medicine and dentistry for its anesthetic and analgesic effects. It induces euphoria, which is why it is associated with laughter.
Based on the above analysis, the correct option is:
Nitrous oxide
Conclusion: Nitrous oxide, also known as laughing gas, is used for its anesthetic properties, and it can create a feeling of euphoria or laughter when inhaled, hence its name. Thus, the correct answer is "Nitrous oxide."
