bond length in but-1,3-diene is:

View answer and explanation

Correct option: D

1.34\mathop \mathrm{A}\limits^ \circ

Option D (

1.34\mathop \mathrm{A}\limits^ \circ

) is correct because the C2-C3 bond in but-1,3-diene has partial double bond character due to resonance, resulting in a bond length shorter than a typical single bond.
