Multiple choice

Which of the following statements regarding the 1, 3-butadiene is/are false? A. The hybridisation of Carbon atom number 1 and 4 is sp2. B. The single bond between carbon atom number 2 and 3 is of the same length as the C-C bond length in ethane. C. 1, 3-butadiene is a conjugated diene.

  1. Only A

  2. Only B

  3. Only C

  4. Only B and C

  5. None of these

B Correct answer
Explanation

Due to resonance C2-C3 bond has some double bond character, and hence its bond length (1.46 Ǻ) is shorter than the C-C bond length in ethane (1.54 Ǻ). Thus this option is correct.
