Sulfenic acid

Citric acid

Nitric acid

Sulphuric acid

- When an onion is cut, it triggers the release of a natural enzyme called synthase.

- This enzyme converts the amino acid sulfoxides present in onion cells into sulfenic acid.

- Sulfenic acid is a volatile compound that further reacts to form the compounds causing the irritation and tears.

- Citric acid is commonly found in citrus fruits and is not related to onions.

- Nitric acid is a strong acid used in fertilizers and is unrelated to onion chemistry.

- Sulphuric acid is a strong acid used in industrial processes, not naturally occurring in onions.

Your answer is option:1- Sulfenic acid.
