Determine the total number of pi () bonds present in one molecule of Hexa-1,3-dien-5-yne. — IUPAC and Nomenclature Chemistry Question

💡 Solution & Explanation

The structure contains two double bonds (dien) and one triple bond (yne). Each double bond contains 1 $\pi$ bond ($2 \times 1 = 2$). The triple bond contains 2 $\pi$ bonds. Total $\pi$ bonds = $2 + 2 = 4$.
