'propene sulphilin' is the chemical substance present in the onion which makes you to cry when you cut onion.
A combination of sulfuric acid, sulfur dioxide and hydrogen sulfide
this was taken from another article
This compound is syn-propanethial S-oxide (C3H6OS).

It is not the strong odor of the onion that makes us cry, but the gas that the onion releases when we sever this member of the lily family. The onion itself contains oil, which contains sulfur, an irritant to both our noses and to our eyes. Cutting an onion arouses a gas contained within the onion, propanethiol S-oxide, which then couples with the enzymes in the onion to emit a passive sulfur compound. When this upwardly mobile gas encounters the water produced by the tear ducts in our eyelids, it produces sulfuric acid. In response to the caustic acid, our eyes automatically blink, and produce tears which irrigate the eye, and which flush out the sulfuric acid. Another reflex to rid the eyes of a foreign substance, that of rubbing our eyes with our hands, often exacerbates the situation, because our hands are coated with the caustic, sulfuric acid producing oil from cutting the onion, which we then rub directly into our eyes. Much to our chagrin, the only remedy for ridding the onion of its pungent, irritating oil is to boil it, not to slice it or dice it.
The main reason pepper makes us sneeze is that it has a coating on it of a chemical called piperine. This is the chemical that makes pepper spicy. When pepper gets inside your nose, this chemical really irritates its lining, triggering your sneeze reflex to expel it. A secondary reason it might make you sneeze is that pepper is usually ground up into tiny bits, which can get in your nose and make you sneeze for the same reason as things like dust.
Well chemical equations can help us understand how a certain substance is made and what combines with what to make it using symbol and word equations .It makes more understanding of the concepts through symbols.
What is chemical energy? Chemical Energy,example: burning paper,most likely school food and
It keeps us warm when we burn firewood and it is the gas that we fuel our cars with.
It's not just purple onions. There is a chemical inside of onions that, when you slice an onion, are released into the air. This causes a slight chemical reaction in your eyes, causing a burning sensation. To combat the burning, your eyes tear, causing you to "cry."

There's an acid which is called Amino Acid Zoologist's in the onion that we smell that activates the cry it's all to do with the chemicals in onions. It triggers certain things( like the smell and the feel) which make us cry.When you cut an onion it breaks the onion's cells and releases a gas called syn-propanethial-S-oxide. The gas reaches your eyes and reacts with the water in it to make a low-grade sulphuric acid. The eye produces tears to wash out the acid.From the Related Link below:"It is not the strong odor of the onion that makes us cry, but the gas that the onion releases when we sever this member of the lily family.

White, yellow, and red onions are much more likely to make us cry than green onions. Onions make us tear up because of a reaction in the vegetable that occurs as we break into it, which causes the release of a chemical called lachrymatory factor, which then irritates our eyes.
