Solution
The reactions show compound A undergoing ozonolysis to produce two carbonyl compounds. Ozonolysis cleaves alkenes at the double bond. The products are a dialdehyde and formaldehyde (HCHO). For an alkene to produce formaldehyde, one end of the double bond must be a terminal CH= group. The dialdehyde structure indicates the original alkene was symmetric. Therefore, compound A must be a symmetric diene with terminal vinyl groups.
Final answer: The first option, 1,5-hexadiene.
