What functional group would be expected to be found in the major, and final, organic product upon completion of the reaction between 1-hexyne and a mixture of mercuric sulfate and aqueous sulfuric acid?

Ketone

Explanation:

The reaction between 1-hexyne and mercuric sulphate in the presences of aqueous sulphuric acid is a reaction that leads to the formation of a product containing a carbonyl group(a ketone in this case).

This reaction occurs in alkynes but the product formed depends on the structure of the alkyne; an aldehyde or ketone may be formed depending on the structure of the alkyne.

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary
