The number of sigma (σ\sigma) and pi (π\pi) bonds in pent-2-en-4-yne (CH3-CH=CH-C≡CH\mathrm{CH_3\text{-}CH{=}CH\text{-}C{\equiv}CH}) is:

  1. A.10 σ\sigma bonds and 3 π\pi bonds✓
  2. B.8 σ\sigma bonds and 5 π\pi bonds
  3. C.11 σ\sigma bonds and 2 π\pi bonds
  4. D.13 σ\sigma bonds and no π\pi bonds

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
