Question

Ch2 doublebond c double bond ch singlebond ch3

Answer 1

Answer:

The longest carbon chain has 4 carbons and hence the root word is But-.

Since double bond gets more priority than triple bond, numbering is done such that carbon containing double bond gets lowest number.(numbering from left to right for this question).

Thus the IUPAC name is But-1-en-3-yne.

That's it…
