Chemistry · Molecular Orbital Theory: Its important features, LCAOs, types of molecular orbitals (bonding, antibonding), sigma and pi-bonds
The number of bonds and bonds in 1, 3-butadiene are respectively:
The number of \( \sigma \) bonds and \( \pi \) bonds in 1, 3-butadiene are respectively:
- A. 9 and 2
- B. 6 and 2
- C. 9 \) and 6
- D. none of these
Step-by-step solution
1,3-butadiene (CH2=CH-CH=CH2) has 9 σ bonds: 3 C-C σ bonds (one from the single bond and one from each double bond) and 6 C-H σ bonds (2 on each terminal carbon, 1 on each internal carbon). It has 2 π bonds, one from each double bond.
