The number of isomeric tetraenes (NOT containing sp-hybridized carbon atoms) that can be formed from the following reaction sequence is ____.
Answer: 2
Solution
The reaction sequence involves elimination reactions that produce conjugated tetraenes. Analyzing the substrate and the elimination conditions, two distinct isomeric tetraenes (differing in the geometry of double bonds) can be formed that do not contain sp-hybridized carbons.
