Actually what happens when we cut onion....
When we cut an onion , it cells broke and release an enzyme which contains sulfenic acid. Sulphenic acid is very unstable it evaporates easily.The evaporated gas reaches our eyes and reacts with water in our eye producing sulfuric acid.This sulfuric acid irritates our eyes.To relieve from this irritation our eyes will start to produce tears.
