Vedclass · Answer

(A) The carbon suboxide molecule, $C_3O_2$, consists of a linear chain of three carbon atoms with two oxygen atoms attached to the terminal carbons.Each carbon atom must satisfy the octet rule and form four bonds.The total number of valence electrons is $3 	imes 4 + 2 	imes 6 = 24$.The structure $O=C=C=C=O$ satisfies the octet rule for all atoms, where each carbon atom is $sp$ hybridized and each oxygen atom has two lone pairs.
