Question

While cutting an onion eye irritation occurs and tears flows down. What can yous urely say? a) Few chemicals inside the ononin are volatile and reach eyes in gaseous state. b) All the chemicals inside the onion are volatile and reach to eyes in gaseous stae. All the chemicals inside the onino are non- volatile and reach to the eyes in the liquid state

Answer 1

Explanation:

Peeling, cutting or crushing an onion's tissue releases enzymes called allinases, which convert these molecules to sulfenic acids. The sulfenic acids, in turn, spontaneously rearrange to form syn-propanethial-S-oxide, the chemical that triggers the tears.The synthase enzyme converts the amino acids sulfoxides of the onion into sulfenic acid.

The unstable sulfenic acid rearranges itself into syn-ropanethial-S-oxide. - Syn-propanethial-S-oxide gets into the air and comes in contact with our eyes. The lachrymal glands in our eyes become irritated and produces tears!
