Question

Which gas does the onion has ​

Answer 1

Answer:

propanethiol S-oxide

While chopping onions, cells inside the onion are broken and the gas that comes out forms sulfenic acid. The acid gets mixed with enzymes and forms a gas called propanethiol S-oxide. When this gas reaches our eyes, it gets mixed with water and forms sulphuric acid.

Answer 2

Explanation:

When an onion breaks apart, the sulfoxides and onion enzymes are released, and this creates sulfenic acid. The sulfenic acid and onion enzymes react and create syn-propanethial-S-oxide—a tough-to-pronounce gas. This gas floats up from the chopped (or bitten) onion and deters critters (and causes humans to shed tears).
