NEETChemistryChemical Bonding and Molecular StructureMCQ+4 / −1
The number of sigma (σ\sigmaσ) and pi (π\piπ) bonds in pent-2-en-4-yne is -
  1. A
    11 σ\sigmaσ bonds and 2 π\piπ bonds
  2. B
    13 σ\sigmaσ bonds and no π\piπ bonds
  3. C
    10 σ\sigmaσ bonds and 3 π\piπ bonds
  4. D
    8 σ\sigmaσ bonds and 5 π\piπ bonds
