Which outcome occurs when pi-bonds rupture in butadiene?

💡 Explanation

When pi-bonds break, free rotation occurs around the sigma bond because the pi-bond's electron density preventing it is removed, the enabling of rotation is observed; therefore, rotation is the result, rather than structure change, under mild conditions.
