Which of the following statements is true about this molecule ?
A.C1—C2 and C3—C4 bonds are of same length
B.C1—C2 bond is shorter than C3—C4 bond✓ Correct
C.C1—C2 bond is longer than C3—C4 bond
D.C1—C2 and C2—C3 bonds are of same length
Explanation
3 4 C C b double bond is in conjugation with both the double bonds on either side but 1 2 C C in only in conjugation with 3 4 C C . So, bond length of 3 4 C C will be longer.
