CHM 102 Introductory Reaction Mechanism and Kinetics Objective Question

Question

In the resonance hybrid of 1,3-butadiene, what is the bond order between C2 and C3?
Options
A 1 (pure single bond)
B 2 (pure double bond)
C Between 1 and 2 (partial double bond character)
Correct Answer
D 0 (no bond)
Correct Answer

Option C is the correct answer.

Detailed Explanation

In 1,3-butadiene, resonance delocalization gives the central C2-C3 bond partial double bond character (bond order >1), making it shorter than a typical single bond.

Hint

Resonance leads to bond equalization.
