Chapter 24, Problem 24.36P

Interpretation Introduction

Interpretation:

The product of the given reaction, assuming the reaction takes place via $\text{[6 + 4]}$ cycloaddition, is to be drawn.

Concept introduction:

The $\text{[6 + 4]}$ cycloaddition completes with movement of $\text{10 π-electrons}$ and thus requires five curved arrows. In this reaction, $\text{6π}$ electrons are involved from one reactant and $\text{4π}$ electrons from the other. Two C=C double bonds break to form two C-C single bonds.
