<u>Answer:</u> The percent yield of the compound is 30.86 %.
<u>Explanation:</u>
To calculate the percentage yield of a compound, we use the equation:

Experimental yield of compound = 25 g
Theoretical yield of compound = 81 g
Putting values in above equation, we get:

Hence, the percent yield of the compound is 30.86 %.
Answer:
The answer is below
Explanation:
Ketone is a class of organic compounds which has a carbonyl group such that the carbon atom is covalently bonded to an oxygen atom, while the remaining two bonds are to other carbon atoms or hydrocarbon radicals.
Ketones are highly reactive hydrocarbons, they can be gotten from the oxidization of secondary alcohols. Ketone are used for medicinal applications.
The third option is the ketone
