Chapter 24, Problem 93

(choose chapter or problem)

Carbon suboxide, \(\mathrm{C}_{3} \mathrm{O}_{2}\), is a linear molecule with the two oxygen atoms at the end and double bonds between each carbon and oxygen atom.

a. Draw the Lewis structure for \(\mathrm{C}_{3} \mathrm{O}_{2}\).

b. State the type of hybridization of each carbon atom.

c. Calculate the heat of reaction for the reaction of carbon suboxide with water to form malonic acid \(\left(\mathrm{HO}_{2} \mathrm{CCH}_{2} \mathrm{CO}_{2} \mathrm{H}\right)\). Hint: Each end of malonic acid has a carbon double bonded to an oxygen and to a hydroxide.
